    Replication guide
    =================
    
    Step 0 - prerequisites
    ----------------------
    
    - Unix-compatible OS (Linux or OS X)
    - Python interpreter (2.7 was used; Python 3 compatibility is highly likely)
    - R 3.4 or higher (3.4.4 was used, 3.2 is known to be incompatible)
    
    Depending on detalization level (see Step 2 for more details):
    - up to 2Tb of disk space (see Step 2 detalization levels)
    - at least 16Gb of RAM (64 preferable)
    - few hours to few month of processing time
    
    Step 1 - software
    ----------------
    
    - unpack **ghd-0.1.0.zip**, or clone from gitlab:
    
       git clone https://gitlab.com/user2589/ghd.git
       git checkout 0.1.0
     
     `cd` into the extracted folder. 
     All commands below assume it as a current directory.
      
    - copy `settings.py` into the extracted folder. Edit the file:
      * set `DATASET_PATH` to some newly created folder path
      * add at least one GitHub API token to `SCRAPER_GITHUB_API_TOKENS` 
    - install docker. For Ubuntu Linux, the command is 
      `sudo apt-get install docker-compose`
    - install libarchive and headers: `sudo apt-get install libarchive-dev`
    - (optional) to replicate on NPM, install yajl: `sudo apt-get install yajl-tools`
     Without this dependency, you might get an error on the next step, 
     but it's safe to ignore.
    - install Python libraries: `pip install --user -r requirements.txt` . 
    - disable all APIs except GitHub (Bitbucket and Gitlab support were
     not yet implemented when this study was in progress): edit
     `scraper/init.py`, comment out everything except GitHub support
     in `PROVIDERS`.
    
    Step 2 - obtaining the dataset
    -----------------------------
    
    The ultimate goal of this step is to get output of the Python function 
    `common.utils.survival_data()` and save it into a CSV file:
    
      # copy and paste into a Python console
      from common import utils
      survival_data = utils.survival_data('pypi', '2008', smoothing=6)
      survival_data.to_csv('survival_data.csv')
    
    Since full replication will take several months, here are some ways to speedup
    the process:
    
    ####Option 2.a, difficulty level: easiest
    
    Just use the precomputed data. Step 1 is not necessary under this scenario.
    
    - extract **dataset_minimal_Jan_2018.zip**
    - get `survival_data.csv`, go to the next step
    
    ####Option 2.b, difficulty level: easy
    
    Use precomputed longitudinal feature values to build the final table.
    The whole process will take 15..30 minutes.
    
    - create a folder `

    Description

    Context

    To make this a seamless process, I cleaned the data and delete many variables that I thought were not important to our dataset. I then uploaded all of those files to Kaggle for each of you to download. The rideshare_data has both lyft and uber but it is still a cleaned version from the dataset we downloaded from Kaggle.

    Use of Data Files

    You can easily subset the data into the car types that you will be modeling by first loading the csv into R, here is the code for how you do this:

    This loads the file into R

    df<-read.csv('uber.csv')

    The next codes is to subset the data into specific car types. The example below only has Uber 'Black' car types.

    df_black<-subset(uber_df, uber_df$name == 'Black')

    This next portion of code will be to load it into R. First, we must write this dataframe into a csv file on our computer in order to load it into R.

    write.csv(df_black, "nameofthefileyouwanttosaveas.csv")

    The file will appear in you working directory. If you are not familiar with your working directory. Run this code:

    getwd()

    The output will be the file path to your working directory. You will find the file you just created in that folder.

    Inspiration

    Your data will be in front of the world's largest data science community. What questions do you want to see answered?

    Description

    This dataset includes all the data and R code needed to reproduce the analyses in a forthcoming manuscript:Copes, W. E., Q. D. Read, and B. J. Smith. Environmental influences on drying rate of spray applied disinfestants from horticultural production services. PhytoFrontiers, DOI pending.Study description: Instructions for disinfestants typically specify a dose and a contact time to kill plant pathogens on production surfaces. A problem occurs when disinfestants are applied to large production areas where the evaporation rate is affected by weather conditions. The common contact time recommendation of 10 min may not be achieved under hot, sunny conditions that promote fast drying. This study is an investigation into how the evaporation rates of six commercial disinfestants vary when applied to six types of substrate materials under cool to hot and cloudy to sunny weather conditions. Initially, disinfestants with low surface tension spread out to provide 100% coverage and disinfestants with high surface tension beaded up to provide about 60% coverage when applied to hard smooth surfaces. Disinfestants applied to porous materials were quickly absorbed into the body of the material, such as wood and concrete. Even though disinfestants evaporated faster under hot sunny conditions than under cool cloudy conditions, coverage was reduced considerably in the first 2.5 min under most weather conditions and reduced to less than or equal to 50% coverage by 5 min. Dataset contents: This dataset includes R code to import the data and fit Bayesian statistical models using the model fitting software CmdStan, interfaced with R using the packages brms and cmdstanr. The models (one for 2022 and one for 2023) compare how quickly different spray-applied disinfestants dry, depending on what chemical was sprayed, what surface material it was sprayed onto, and what the weather conditions were at the time. Next, the statistical models are used to generate predictions and compare mean drying rates between the disinfestants, surface materials, and weather conditions. Finally, tables and figures are created. These files are included:Drying2022.csv: drying rate data for the 2022 experimental runWeather2022.csv: weather data for the 2022 experimental runDrying2023.csv: drying rate data for the 2023 experimental runWeather2023.csv: weather data for the 2023 experimental rundisinfestant_drying_analysis.Rmd: RMarkdown notebook with all data processing, analysis, and table creation codedisinfestant_drying_analysis.html: rendered output of notebookMS_figures.R: additional R code to create figures formatted for journal requirementsfit2022_discretetime_weather_solar.rds: fitted brms model object for 2022.

    Description

    Objective: To develop a clinical informatics pipeline designed to capture large-scale structured EHR data for a national patient registry.

    Materials and Methods: The EHR-R-REDCap pipeline is implemented using R-statistical software to remap and import structured EHR data into the REDCap-based multi-institutional Merkel Cell Carcinoma (MCC) Patient Registry using an adaptable data dictionary.

    Results: Clinical laboratory data were extracted from EPIC Clarity across several participating institutions. Labs were transformed, remapped and imported into the MCC registry using the EHR labs abstraction (eLAB) pipeline. Forty-nine clinical tests encompassing 482,450 results were imported into the registry for 1,109 enrolled MCC patients. Data-quality assessment revealed highly accurate, valid labs. Univariate modeling was performed for labs at baseline on overall survival (N=176) using this clinical informatics pipeline.

    Conclusion: We demonstrate feasibility of the facile eLAB workflow. EHR data is successfully transformed, and bulk-loaded/imported into a REDCap-based national registry to execute real-world data analysis and interoperability.

    Methods eLAB Development and Source Code (R statistical software):

    eLAB is written in R (version 4.0.3), and utilizes the following packages for processing: DescTools, REDCapR, reshape2, splitstackshape, readxl, survival, survminer, and tidyverse. Source code for eLAB can be downloaded directly (https://github.com/TheMillerLab/eLAB).

    eLAB reformats EHR data abstracted for an identified population of patients (e.g. medical record numbers (MRN)/name list) under an Institutional Review Board (IRB)-approved protocol. The MCCPR does not host MRNs/names and eLAB converts these to MCCPR assigned record identification numbers (record_id) before import for de-identification.

    Functions were written to remap EHR bulk lab data pulls/queries from several sources including Clarity/Crystal reports or institutional EDW including Research Patient Data Registry (RPDR) at MGB. The input, a csv/delimited file of labs for user-defined patients, may vary. Thus, users may need to adapt the initial data wrangling script based on the data input format. However, the downstream transformation, code-lab lookup tables, outcomes analysis, and LOINC remapping are standard for use with the provided REDCap Data Dictionary, DataDictionary_eLAB.csv. The available R-markdown ((https://github.com/TheMillerLab/eLAB) provides suggestions and instructions on where or when upfront script modifications may be necessary to accommodate input variability.

    The eLAB pipeline takes several inputs. For example, the input for use with the ‘ehr_format(dt)’ single-line command is non-tabular data assigned as R object ‘dt’ with 4 columns: 1) Patient Name (MRN), 2) Collection Date, 3) Collection Time, and 4) Lab Results wherein several lab panels are in one data frame cell. A mock dataset in this ‘untidy-format’ is provided for demonstration purposes (https://github.com/TheMillerLab/eLAB).

    Bulk lab data pulls often result in subtypes of the same lab. For example, potassium labs are reported as “Potassium,” “Potassium-External,” “Potassium(POC),” “Potassium,whole-bld,” “Potassium-Level-External,” “Potassium,venous,” and “Potassium-whole-bld/plasma.” eLAB utilizes a key-value lookup table with ~300 lab subtypes for remapping labs to the Data Dictionary (DD) code. eLAB reformats/accepts only those lab units pre-defined by the registry DD. The lab lookup table is provided for direct use or may be re-configured/updated to meet end-user specifications. eLAB is designed to remap, transform, and filter/adjust value units of semi-structured/structured bulk laboratory values data pulls from the EHR to align with the pre-defined code of the DD.

    Data Dictionary (DD)

    EHR clinical laboratory data is captured in REDCap using the ‘Labs’ repeating instrument (Supplemental Figures 1-2). The DD is provided for use by researchers at REDCap-participating institutions and is optimized to accommodate the same lab-type captured more than once on the same day for the same patient. The instrument captures 35 clinical lab types. The DD serves several major purposes in the eLAB pipeline. First, it defines every lab type of interest and associated lab unit of interest with a set field/variable name. It also restricts/defines the type of data allowed for entry for each data field, such as a string or numerics. The DD is uploaded into REDCap by every participating site/collaborator and ensures each site collects and codes the data the same way. Automation pipelines, such as eLAB, are designed to remap/clean and reformat data/units utilizing key-value look-up tables that filter and select only the labs/units of interest. eLAB ensures the data pulled from the EHR contains the correct unit and format pre-configured by the DD. The use of the same DD at every participating site ensures that the data field code, format, and relationships in the database are uniform across each site to allow for the simple aggregation of the multi-site data. For example, since every site in the MCCPR uses the same DD, aggregation is efficient and different site csv files are simply combined.

    Study Cohort

    This study was approved by the MGB IRB. Search of the EHR was performed to identify patients diagnosed with MCC between 1975-2021 (N=1,109) for inclusion in the MCCPR. Subjects diagnosed with primary cutaneous MCC between 2016-2019 (N= 176) were included in the test cohort for exploratory studies of lab result associations with overall survival (OS) using eLAB.

    Statistical Analysis

    OS is defined as the time from date of MCC diagnosis to date of death. Data was censored at the date of the last follow-up visit if no death event occurred. Univariable Cox proportional hazard modeling was performed among all lab predictors. Due to the hypothesis-generating nature of the work, p-values were exploratory and Bonferroni corrections were not applied.

    Description

    This archive contains code and data for reproducing the analysis for “Replication Data for Revisiting ‘The Rise and Decline’ in a Population of Peer Production Projects”. Depending on what you hope to do with the data you probabbly do not want to download all of the files. Depending on your computation resources you may not be able to run all stages of the analysis. The code for all stages of the analysis, including typesetting the manuscript and running the analysis, is in code.tar. If you only want to run the final analysis or to play with datasets used in the analysis of the paper, you want intermediate_data.7z or the uncompressed tab and csv files. The data files are created in a four-stage process. The first stage uses the program “wikiq” to parse mediawiki xml dumps and create tsv files that have edit data for each wiki. The second stage generates all.edits.RDS file which combines these tsvs into a dataset of edits from all the wikis. This file is expensive to generate and at 1.5GB is pretty big. The third stage builds smaller intermediate files that contain the analytical variables from these tsv files. The fourth stage uses the intermediate files to generate smaller RDS files that contain the results. Finally, knitr and latex typeset the manuscript. A stage will only run if the outputs from the previous stages do not exist. So if the intermediate files exist they will not be regenerated. Only the final analysis will run. The exception is that stage 4, fitting models and generating plots, always runs. If you only want to replicate from the second stage onward, you want wikiq_tsvs.7z. If you want to replicate everything, you want wikia_mediawiki_xml_dumps.7z.001 wikia_mediawiki_xml_dumps.7z.002, and wikia_mediawiki_xml_dumps.7z.003. These instructions work backwards from building the manuscript using knitr, loading the datasets, running the analysis, to building the intermediate datasets. Building the manuscript using knitr This requires working latex, latexmk, and knitr installations. Depending on your operating system you might install these packages in different ways. On Debian Linux you can run apt install r-cran-knitr latexmk texlive-latex-extra. Alternatively, you can upload the necessary files to a project on Overleaf.com. Download code.tar. This has everything you need to typeset the manuscript. Unpack the tar archive. On a unix system this can be done by running tar xf code.tar. Navigate to code/paper_source. Install R dependencies. In R. run install.packages(c("data.table","scales","ggplot2","lubridate","texreg")) On a unix system you should be able to run make to build the manuscript generalizable_wiki.pdf. Otherwise you should try uploading all of the files (including the tables, figure, and knitr folders) to a new project on Overleaf.com. Loading intermediate datasets The intermediate datasets are found in the intermediate_data.7z archive. They can be extracted on a unix system using the command 7z x intermediate_data.7z. The files are 95MB uncompressed. These are RDS (R data set) files and can be loaded in R using the readRDS. For example newcomer.ds <- readRDS("newcomers.RDS"). If you wish to work with these datasets using a tool other than R, you might prefer to work with the .tab files. Running the analysis Fitting the models may not work on machines with less than 32GB of RAM. If you have trouble, you may find the functions in lib-01-sample-datasets.R useful to create stratified samples of data for fitting models. See line 89 of 02_model_newcomer_survival.R for an example. Download code.tar and intermediate_data.7z to your working folder and extract both archives. On a unix system this can be done with the command tar xf code.tar && 7z x intermediate_data.7z. Install R dependencies. install.packages(c("data.table","ggplot2","urltools","texreg","optimx","lme4","bootstrap","scales","effects","lubridate","devtools","roxygen2")). On a unix system you can simply run regen.all.sh to fit the models, build the plots and create the RDS files. Generating datasets Building the intermediate files The intermediate files are generated from all.edits.RDS. This process requires about 20GB of memory. Download all.edits.RDS, userroles_data.7z,selected.wikis.csv, and code.tar. Unpack code.tar and userroles_data.7z. On a unix system this can be done using tar xf code.tar && 7z x userroles_data.7z. Install R dependencies. In R run install.packages(c("data.table","ggplot2","urltools","texreg","optimx","lme4","bootstrap","scales","effects","lubridate","devtools","roxygen2")). Run 01_build_datasets.R. Building all.edits.RDS The intermediate RDS files used in the analysis are created from all.edits.RDS. To replicate building all.edits.RDS, you only need to run 01_build_datasets.R when the int...

For this data extraction I recommend, to click always on the bottom line of the red rectangle, as there is always data available due to a dummy variable ("lin") that creates continuous data at the bottom of the active panel. The data are captured only if greenish vertical bar appears and if new line of data appears in R console). # 3 - to extract incubation bouts, first click in the new plot has to be start of incubation, then next click depict end of incubation and the click on the same stop start of the incubation for the other sex. If the end and start of incubation are at different times, the data will be still extracted, but the sex, logger and bird_ID will be wrong. These need to be changed manually in the csv file. Similarly, the first bout for a given plot will be always assigned to male (if no data are present in the csv file) or based on previous data. Hence, whenever a data from a new plot are extracted, at a first mouse click it is worth checking whether the sex, logger and bird_ID information is correct and if not adjust it manually. # 4 - if all information from one day (panel) is extracted, right-click on the plot and choose "stop".

    Description

    Overview

    This dataset is the repository for the following paper submitted to Data in Brief:

    Kempf, M. A dataset to model Levantine landcover and land-use change connected to climate change, the Arab Spring and COVID-19. Data in Brief (submitted: December 2023).

    The Data in Brief article contains the supplement information and is the related data paper to:

    Kempf, M. Climate change, the Arab Spring, and COVID-19 - Impacts on landcover transformations in the Levant. Journal of Arid Environments (revision submitted: December 2023).

    Description/abstract

    The Levant region is highly vulnerable to climate change, experiencing prolonged heat waves that have led to societal crises and population displacement. Since 2010, the area has been marked by socio-political turmoil, including the Syrian civil war and currently the escalation of the so-called Israeli-Palestinian Conflict, which strained neighbouring countries like Jordan due to the influx of Syrian refugees and increases population vulnerability to governmental decision-making. Jordan, in particular, has seen rapid population growth and significant changes in land-use and infrastructure, leading to over-exploitation of the landscape through irrigation and construction. This dataset uses climate data, satellite imagery, and land cover information to illustrate the substantial increase in construction activity and highlights the intricate relationship between climate change predictions and current socio-political developments in the Levant.

    Folder structure

    The main folder after download contains all data, in which the following subfolders are stored are stored as zipped files:

    “code” stores the above described 9 code chunks to read, extract, process, analyse, and visualize the data.

    “MODIS_merged” contains the 16-days, 250 m resolution NDVI imagery merged from three tiles (h20v05, h21v05, h21v06) and cropped to the study area, n=510, covering January 2001 to December 2022 and including January and February 2023.

    “mask” contains a single shapefile, which is the merged product of administrative boundaries, including Jordan, Lebanon, Israel, Syria, and Palestine (“MERGED_LEVANT.shp”).

    “yield_productivity” contains .csv files of yield information for all countries listed above.

    “population” contains two files with the same name but different format. The .csv file is for processing and plotting in R. The .ods file is for enhanced visualization of population dynamics in the Levant (Socio_cultural_political_development_database_FAO2023.ods).

    “GLDAS” stores the raw data of the NASA Global Land Data Assimilation System datasets that can be read, extracted (variable name), and processed using code “8_GLDAS_read_extract_trend” from the respective folder. One folder contains data from 1975-2022 and a second the additional January and February 2023 data.

    “built_up” contains the landcover and built-up change data from 1975 to 2022. This folder is subdivided into two subfolder which contain the raw data and the already processed data. “raw_data” contains the unprocessed datasets and “derived_data” stores the cropped built_up datasets at 5 year intervals, e.g., “Levant_built_up_1975.tif”.

    Code structure

    1_MODIS_NDVI_hdf_file_extraction.R


    This is the first code chunk that refers to the extraction of MODIS data from .hdf file format. The following packages must be installed and the raw data must be downloaded using a simple mass downloader, e.g., from google chrome. Packages: terra. Download MODIS data from after registration from: https://lpdaac.usgs.gov/products/mod13q1v061/ or https://search.earthdata.nasa.gov/search (MODIS/Terra Vegetation Indices 16-Day L3 Global 250m SIN Grid V061, last accessed, 09th of October 2023). The code reads a list of files, extracts the NDVI, and saves each file to a single .tif-file with the indication “NDVI”. Because the study area is quite large, we have to load three different (spatially) time series and merge them later. Note that the time series are temporally consistent.


    2_MERGE_MODIS_tiles.R


    In this code, we load and merge the three different stacks to produce large and consistent time series of NDVI imagery across the study area. We further use the package gtools to load the files in (1, 2, 3, 4, 5, 6, etc.). Here, we have three stacks from which we merge the first two (stack 1, stack 2) and store them. We then merge this stack with stack 3. We produce single files named NDVI_final_*consecutivenumber*.tif. Before saving the final output of single merged files, create a folder called “merged” and set the working directory to this folder, e.g., setwd("your directory_MODIS/merged").


    3_CROP_MODIS_merged_tiles.R


    Now we want to crop the derived MODIS tiles to our study area. We are using a mask, which is provided as .shp file in the repository, named "MERGED_LEVANT.shp". We load the merged .tif files and crop the stack with the vector. Saving to individual files, we name them “NDVI_merged_clip_*consecutivenumber*.tif. We now produced single cropped NDVI time series data from MODIS.
    The repository provides the already clipped and merged NDVI datasets.


    4_TREND_analysis_NDVI.R


    Now, we want to perform trend analysis from the derived data. The data we load is tricky as it contains 16-days return period across a year for the period of 22 years. Growing season sums contain MAM (March-May), JJA (June-August), and SON (September-November). December is represented as a single file, which means that the period DJF (December-February) is represented by 5 images instead of 6. For the last DJF period (December 2022), the data from January and February 2023 can be added. The code selects the respective images from the stack, depending on which period is under consideration. From these stacks, individual annually resolved growing season sums are generated and the slope is calculated. We can then extract the p-values of the trend and characterize all values with high confidence level (0.05). Using the ggplot2 package and the melt function from reshape2 package, we can create a plot of the reclassified NDVI trends together with a local smoother (LOESS) of value 0.3.
    To increase comparability and understand the amplitude of the trends, z-scores were calculated and plotted, which show the deviation of the values from the mean. This has been done for the NDVI values as well as the GLDAS climate variables as a normalization technique.


    5_BUILT_UP_change_raster.R


    Let us look at the landcover changes now. We are working with the terra package and get raster data from here: https://ghsl.jrc.ec.europa.eu/download.php?ds=bu (last accessed 03. March 2023, 100 m resolution, global coverage). Here, one can download the temporal coverage that is aimed for and reclassify it using the code after cropping to the individual study area. Here, I summed up different raster to characterize the built-up change in continuous values between 1975 and 2022.


    6_POPULATION_numbers_plot.R


    For this plot, one needs to load the .csv-file “Socio_cultural_political_development_database_FAO2023.csv” from the repository. The ggplot script provided produces the desired plot with all countries under consideration.


    7_YIELD_plot.R


    In this section, we are using the country productivity from the supplement in the repository “yield_productivity” (e.g., "Jordan_yield.csv". Each of the single country yield datasets is plotted in a ggplot and combined using the patchwork package in R.


    8_GLDAS_read_extract_trend


    The last code provides the basis for the trend analysis of the climate variables used in the paper. The raw data can be accessed https://disc.gsfc.nasa.gov/datasets?keywords=GLDAS%20Noah%20Land%20Surface%20Model%20L4%20monthly&page=1 (last accessed 9th of October 2023). The raw data comes in .nc file format and various variables can be extracted using the [“^a variable name”] command from the spatraster collection. Each time you run the code, this variable name must be adjusted to meet the requirements for the variables (see this link for abbreviations: https://disc.gsfc.nasa.gov/datasets/GLDAS_CLSM025_D_2.0/summary, last accessed 09th of October 2023; or the respective code chunk when reading a .nc file with the ncdf4 package in R) or run print(nc) from the code or use names(the spatraster collection).
    Choosing one variable, the code uses the MERGED_LEVANT.shp mask from the repository to crop and mask the data to the outline of the study area.
    From the processed data, trend analysis are conducted and z-scores were calculated following the code described above. However, annual trends require the frequency of the time series analysis to be set to value = 12. Regarding, e.g., rainfall, which is measured as annual sums and not means, the chunk r.sum=r.sum/12 has to be removed or set to r.sum=r.sum/1 to avoid calculating annual mean values (see other variables). Seasonal subset can be calculated as described in the code. Here, 3-month subsets were chosen for growing seasons, e.g. March-May (MAM), June-July (JJA), September-November (SON), and DJF (December-February, including Jan/Feb of the consecutive year).
    From the data, mean values of 48 consecutive years are calculated and trend analysis are performed as describe above. In the same way, p-values are extracted and 95 % confidence level values are marked with dots on the raster plot. This analysis can be performed with a much longer time series, other variables, ad different spatial extent across the globe due to the availability of the GLDAS variables.

    Description

    Welcome to my Kickstarter case study! In this project I’m trying to understand what the success’s factors for a Kickstarter campaign are, analyzing an available public dataset from Web Robots. The process of analysis will follow the data analysis roadmap: ASK, PREPARE, PROCESS, ANALYZE, SHARE and ACT.

    ASK

    Different questions will guide my analysis: 1. Is the campaign duration influencing the success of the project? 2. Is it the chosen funding budget? 3. Which category of campaign is the most likely to be successful?

    PREPARE

    I’m using the Kickstarter Datasets publicly available on Web Robots. Data are scraped using a bot which collects the data in CSV format once a month and all the data are divided into CSV files. Each table contains: - backers_count : number of people that contributed to the campaign - blurb : a captivating text description of the project - category : the label categorizing the campaign (technology, art, etc) - country - created_at : day and time of campaign creation - deadline : day and time of campaign max end - goal : amount to be collected - launched_at : date and time of campaign launch - name : name of campaign - pledged : amount of money collected - state : success or failure of the campaign

    Each month scraping produce a huge amount of CSVs, so for an initial analysis I decided to focus on three months: November and December 2023, and January 2024. I’ve downloaded zipped files which once unzipped contained respectively: 7 CSVs (November 2023), 8 CSVs (December 2023), 8 CSVs (January 2024). Each month was divided into a specific folder.

    Having a first look at the spreadsheets, it’s clear that there is some need for cleaning and modification: for example, dates and times are shown in Unix code, there are multiple columns that are not helpful for the scope of my analysis, currencies need to be uniformed (some are US$, some GB£, etc). In general, I have all the data that I need to answer my initial questions, identify trends, and make predictions.

    PROCESS

    I decided to use R to clean and process the data. For each month I started setting a new working environment in its own folder. After loading the necessary libraries: R library(tidyverse) library(lubridate) library(ggplot2) library(dplyr) library(tidyr) I scripted a general R code that searches for CSVs files in the folder, open them as separate variable and into a single data frame:

    csv_files <- list.files(pattern = "\\.csv$")
    data_frames <- list()
    
    for (file in csv_files) {
     variable_name <- sub("\\.csv$", "", file)
     assign(variable_name, read.csv(file))
     data_frames[[variable_name]] <- get(variable_name)
    }
    

    Next, I converted some columns in numeric values because I was running into types error when trying to merge all the CSVs into a single comprehensive file.

    data_frames <- lapply(data_frames, function(df) {
     df$converted_pledged_amount <- as.numeric(df$converted_pledged_amount)
     return(df)
    })
    data_frames <- lapply(data_frames, function(df) {
     df$usd_exchange_rate <- as.numeric(df$usd_exchange_rate)
     return(df)
    })
    data_frames <- lapply(data_frames, function(df) {
     df$usd_pledged <- as.numeric(df$usd_pledged)
     return(df)
    })
    

    In each folder I then ran a command to merge the CSVs in a single file (one for November 2023, one for December 2023 and one for January 2024):

    all_nov_2023 = bind_rows(data_frames)
    all_dec_2023 = bind_rows(data_frames)
    all_jan_2024 = bind_rows(data_frames)`
    

    After merging I converted the UNIX code datestamp into a readable datetime for the columns “created”, “launched”, “deadline” and deleted all the columns that had these data set to 0. I also filtered the values into the “slug” columns to show only the category of the campaign, without unnecessary information for the scope of my analysis. The final table was then saved.

    filtered_dec_2023 <- all_dec_2023 %>% #this was modified according to the considered month
     select(blurb, backers_count, category, country, created_at, launched_at, deadline,currency, usd_exchange_rate, goal, pledged, state) %>%
     filter(created_at != 0 & deadline != 0 & launched_at != 0) %>% 
     mutate(category_slug = sub('.*?"slug":"(.*?)".*', '\\1', category)) %>% 
     mutate(created = as.POSIXct(created_at, origin = "1970-01-01")) %>% 
     mutate(launched = as.POSIXct(launched_at, origin = "1970-01-01")) %>% 
     mutate(setted_deadline = as.POSIXct(deadline, origin = "1970-01-01")) %>% 
     select(-category, -deadline, -launched_at, -created_at) %>% 
     relocate(created, launched, setted_deadline, .before = goal)
    
    write.csv(filtered_dec_2023, "filtered_dec_2023.csv", row.names = FALSE)
    
    

    The three generated files were then merged into one comprehensive CSV called "kickstarter_cleaned" which was further modified, converting a...

    Description

    Context

    From World Health Organization - On 31 December 2019, WHO was alerted to several cases of pneumonia in Wuhan City, Hubei Province of China. The virus did not match any other known virus. This raised concern because when a virus is new, we do not know how it affects people.

    So daily level information on the affected people can give some interesting insights when it is made available to the broader data science community.

    The European Centre for Disease Prevention and Control released historical data (to 14 December 2020) on the daily number of new reported COVID-19 cases and deaths worldwide.

    Content

    The attributes of the dataset are the following: 1) dateRep: Date of the report

    2) year_week: Week of the year

    3) cases_weekly: Number of cases during the week

    4) deaths_weekly: Number of deaths during the week

    5) countriesAndTerritories: Country/Territory where the data was reported

    6) geoId: Country/Territory id

    7) countryterritoryCode: Country/Territory code

    8) popData2019: Population data of the Country/Territory in 2019

    9) continentExp: Continent of the Country/Territory

    10) notification_rate_per_100000_population_14-days: 14-day cumulative number of reported COVID-19 cases per 100 000 population

    Disclaimer: Population data in the database is taken from Eurostat for Europe and the World Bank for the rest of the world. Disclaimer: Countries that are not listed in these databases have reported no cases to WHO and no cases were identified in the public domain. The formula to calculate the 14-day cumulative number of reported COVID-19 cases per 100 000 population is (New cases over 14 day period)/Population)*100 000.

The script section outlines allow you to jump to particular figures or tables if needed. All analyses were run in R version 4.3.2, with all packages needed listed at the top of each script.If you'd prefer not to re-run models or want to inspect our run outputs, load the Rdata files into the scripts to look at the exact model runs desribed in the paper.The shell script included is for the analysis of public datasets downloaded from the SRA. To re-run this analysis you will need to download these datasets (which we provide details of in the supplementary methods), and re-run the script in a linux environment. We provide the output from this script (mapped reads across host genes and viruses) to make the heatmap produced in the paper (in the SRA_transmission_mapping_analyses.R file).

    Description

    Author: Andrew J. Felton
    Date: 10/29/2024

    This R project contains the primary code and data (following pre-processing in python) used for data production, manipulation, visualization, and analysis, and figure production for the study entitled:

    "Global estimates of the storage and transit time of water through vegetation"

    Please note that 'turnover' and 'transit' are used interchangeably. Also please note that this R project has been updated multiple times as the analysis has updated.

    Data information:

    The data folder contains key data sets used for analysis. In particular:

    "data/turnover_from_python/updated/august_2024_lc/" contains the core datasets used in this study including global arrays summarizing five year (2016-2020) averages of mean (annual) and minimum (monthly) transit time, storage, canopy transpiration, and number of months of data able as both an array (.nc) or data table (.csv). These data were produced in python using the python scripts found in the "supporting_code" folder. The remaining files in the "data" and "data/supporting_data"" folder primarily contain ground-based estimates of storage and transit found in public databases or through a literature search, but have been extensively processed and filtered here. The "supporting_data"" folder also contains annual (2016-2020) MODIS land cover data used in the analysis and contains separate filters containing the original data (.hdf) and then the final process (filtered) data in .nc format. The resulting annual land cover distributions were used in the pre-processing of data in python.

    #Code information

    Python scripts can be found in the "supporting_code" folder.

    Each R script in this project has a role:

    "01_start.R": This script sets the working directory, loads in the tidyverse package (the remaining packages in this project are called using the `::` operator), and can run two other scripts: one that loads the customized functions (02_functions.R) and one for importing and processing the key dataset for this analysis (03_import_data.R).

    "02_functions.R": This script contains custom functions. Load this using the
    `source()` function in the 01_start.R script.

    "03_import_data.R": This script imports and processes the .csv transit data. It joins the mean (annual) transit time data with the minimum (monthly) transit data to generate one dataset for analysis: annual_turnover_2. Load this using the
    `source()` function in the 01_start.R script.

    "04_figures_tables.R": This is the main workhouse for figure/table production and
    supporting analyses. This script generates the key figures and summary statistics
    used in the study that then get saved in the manuscript_figures folder. Note that all
    maps were produced using Python code found in the "supporting_code"" folder.

    "supporting_generate_data.R": This script processes supporting data used in the analysis, primarily the varying ground-based datasets of leaf water content.

    "supporting_process_land_cover.R": This takes annual MODIS land cover distributions and processes them through a multi-step filtering process so that they can be used in preprocessing of datasets in python.

    Complete dataset of “Film Circulation on the International Film Festival Network and the Impact on Global Film Culture”

    A peer-reviewed data paper for this dataset is in review to be published in NECSUS_European Journal of Media Studies - an open access journal aiming at enhancing data transparency and reusability, and will be available from https://necsus-ejms.org/ and https://mediarep.org

    Please cite this when using the dataset.


    Detailed description of the dataset:

    1 Film Dataset: Festival Programs

    The Film Dataset consists a data scheme image file, a codebook and two dataset tables in csv format.

    The codebook (csv file “1_codebook_film-dataset_festival-program”) offers a detailed description of all variables within the Film Dataset. Along with the definition of variables it lists explanations for the units of measurement, data sources, coding and information on missing data.

    The csv file “1_film-dataset_festival-program_long” comprises a dataset of all films and the festivals, festival sections, and the year of the festival edition that they were sampled from. The dataset is structured in the long format, i.e. the same film can appear in several rows when it appeared in more than one sample festival. However, films are identifiable via their unique ID.

    The csv file “1_film-dataset_festival-program_wide” consists of the dataset listing only unique films (n=9,348). The dataset is in the wide format, i.e. each row corresponds to a unique film, identifiable via its unique ID. For easy analysis, and since the overlap is only six percent, in this dataset the variable sample festival (fest) corresponds to the first sample festival where the film appeared. For instance, if a film was first shown at Berlinale (in February) and then at Frameline (in June of the same year), the sample festival will list “Berlinale”. This file includes information on unique and IMDb IDs, the film title, production year, length, categorization in length, production countries, regional attribution, director names, genre attribution, the festival, festival section and festival edition the film was sampled from, and information whether there is festival run information available through the IMDb data.


    2 Survey Dataset

    The Survey Dataset consists of a data scheme image file, a codebook and two dataset tables in csv format.

    The codebook “2_codebook_survey-dataset” includes coding information for both survey datasets. It lists the definition of the variables or survey questions (corresponding to Samoilova/Loist 2019), units of measurement, data source, variable type, range and coding, and information on missing data.

    The csv file “2_survey-dataset_long-festivals_shared-consent” consists of a subset (n=161) of the original survey dataset (n=454), where respondents provided festival run data for films (n=206) and gave consent to share their data for research purposes. This dataset consists of the festival data in a long format, so that each row corresponds to the festival appearance of a film.

    The csv file “2_survey-dataset_wide-no-festivals_shared-consent” consists of a subset (n=372) of the original dataset (n=454) of survey responses corresponding to sample films. It includes data only for those films for which respondents provided consent to share their data for research purposes. This dataset is shown in wide format of the survey data, i.e. information for each response corresponding to a film is listed in one row. This includes data on film IDs, film title, survey questions regarding completeness and availability of provided information, information on number of festival screenings, screening fees, budgets, marketing costs, market screenings, and distribution. As the file name suggests, no data on festival screenings is included in the wide format dataset.


    3 IMDb & Scripts

    The IMDb dataset consists of a data scheme image file, one codebook and eight datasets, all in csv format. It also includes the R scripts that we used for scraping and matching.

    The codebook “3_codebook_imdb-dataset” includes information for all IMDb datasets. This includes ID information and their data source, coding and value ranges, and information on missing data.

    The csv file “3_imdb-dataset_aka-titles_long” contains film title data in different languages scraped from IMDb in a long format, i.e. each row corresponds to a title in a given language.

    The csv file “3_imdb-dataset_awards_long” contains film award data in a long format, i.e. each row corresponds to an award of a given film.

    The csv file “3_imdb-dataset_companies_long” contains data on production and distribution companies of films. The dataset is in a long format, so that each row corresponds to a particular company of a particular film.

    The csv file “3_imdb-dataset_crew_long” contains data on names and roles of crew members in a long format, i.e. each row corresponds to each crew member. The file also contains binary gender assigned to directors based on their first names using the GenderizeR application.

    The csv file “3_imdb-dataset_festival-runs_long” contains festival run data scraped from IMDb in a long format, i.e. each row corresponds to the festival appearance of a given film. The dataset does not include each film screening, but the first screening of a film at a festival within a given year. The data includes festival runs up to 2019.

    The csv file “3_imdb-dataset_general-info_wide” contains general information about films such as genre as defined by IMDb, languages in which a film was shown, ratings, and budget. The dataset is in wide format, so that each row corresponds to a unique film.

    The csv file “3_imdb-dataset_release-info_long” contains data about non-festival release (e.g., theatrical, digital, tv, dvd/blueray). The dataset is in a long format, so that each row corresponds to a particular release of a particular film.

    The csv file “3_imdb-dataset_websites_long” contains data on available websites (official websites, miscellaneous, photos, video clips). The dataset is in a long format, so that each row corresponds to a website of a particular film.

    The dataset includes 8 text files containing the script for webscraping. They were written using the R-3.6.3 version for Windows.

    The R script “r_1_unite_data” demonstrates the structure of the dataset, that we use in the following steps to identify, scrape, and match the film data.

    The R script “r_2_scrape_matches” reads in the dataset with the film characteristics described in the “r_1_unite_data” and uses various R packages to create a search URL for each film from the core dataset on the IMDb website. The script attempts to match each film from the core dataset to IMDb records by first conducting an advanced search based on the movie title and year, and then potentially using an alternative title and a basic search if no matches are found in the advanced search. The script scrapes the title, release year, directors, running time, genre, and IMDb film URL from the first page of the suggested records from the IMDb website. The script then defines a loop that matches (including matching scores) each film in the core dataset with suggested films on the IMDb search page. Matching was done using data on directors, production year (+/- one year), and title, a fuzzy matching approach with two methods: “cosine” and “osa.” where the cosine similarity is used to match titles with a high degree of similarity, and the OSA algorithm is used to match titles that may have typos or minor variations.

    The script “r_3_matching” creates a dataset with the matches for a manual check. Each pair of films (original film from the core dataset and the suggested match from the IMDb website was categorized in the following five categories: a) 100% match: perfect match on title, year, and director; b) likely good match; c) maybe match; d) unlikely match; and e) no match). The script also checks for possible doubles in the dataset and identifies them for a manual check.

    The script “r_4_scraping_functions” creates a function for scraping the data from the identified matches (based on the scripts described above and manually checked). These functions are used for scraping the data in the next script.

    The script “r_5a_extracting_info_sample” uses the function defined in the “r_4_scraping_functions”, in order to scrape the IMDb data for the identified matches. This script does that for the first 100 films, to check, if everything works. Scraping for the entire dataset took a few hours. Therefore, a test with a subsample of 100 films is advisable.

    The script “r_5b_extracting_info_all” extracts the data for the entire dataset of the identified matches.

    The script “r_5c_extracting_info_skipped” checks the films with missing data (where data was not scraped) and tried to extract data one more time to make sure that the errors were not caused by disruptions in the internet connection or other technical issues.

    The script “r_check_logs” is used for troubleshooting and tracking the progress of all of the R scripts used. It gives information on the amount of missing values and errors.


    4 Festival Library Dataset

    The Festival Library Dataset consists of a data scheme image file, one codebook and one dataset, all in csv format.

    The codebook (csv file “4_codebook_festival-library_dataset”) offers a detailed description of all variables within the Library Dataset. It lists the definition of variables, such as location and festival name, and festival categories,

    Description

    The experiment that Farewell and Herzberg (2003) describe is pain-rating experiment that is a subset of the experiment reported by Solomon et al. (1997). It is a two-phase experiment. The first phase is a self-assessment phase in which patients self-assess for pain while moving a painful shoulder joint. The second phase of this experiment is an evaluation phase in which occupational and physical therapy students (the raters) are evaluated for rating patients in a set of videos for pain. The measured response is the difference between a student rating and the patient's rating.


    The R data file plaid.dat.rda contains the data.frame plaid.dat that has a revised version of the data for the Farewell and Herzberg example downloaded from https://doi.org/10.17863/CAM.54494. The comma delimited text file plaid.dat.csv has the same information in this more commonly accepted format, but without the metadata associated with the data.frame<\CODE>.

    The data.frame contains the factors Raters, Viewings, Trainings, Expressiveness, Patients, Occasions, and Motions and a column for the response variable Y. The two factors Viewings and Occasions are additional to those in the downloaded file and the remaining factors have been converted from integers or characters to factors and renamed to the names given above. The column Y is unchanged from the column in the original file.

    To load the data in R use:

    load("plaid.dat.rda") or

    plaid.dat <- read.csv(file = "plaid.dat.csv").

    Description

    This repository contains the datasets and code underpinning Chapter 3 "Counterfactual Impact Evaluation of Plan S" of the report "Galvanising the Open Access Community: A Study on the Impact of Plan S" commissioned by the cOAlition S to scidecode science consulting.

    Two categories of files are part of this repository:

    1. Datasets

    The 21 CSV source files contain the subsets of publications funded by the funding agencies that are part of this study. These files have been provided by OA.Works, with whom scidecode has collaborated for the data collection process. Data sources and collection and processing workflows applied by OA.Works are described on their website and specifically at https://about.oa.report/docs/data.

    The file "plan_s.dta" is the aggregated data file stored in the format ".dta", which can be accessed with STATA by default or with plenty of programming languages using the respective packages, e.g., R or Python.

    2. Code files

    The associated code files that have been used to process the data files are:

     - data_prep_and_analysis_script.do
    - coef_plots_script.R

    The first file has been used to process the CSV data files above for data preparation and analysis purposes. Here, data aggregation and data preprocessing is executed. Furthermore, all statistical regressions for the ounterfactual impact evaluation are listed in this code file. The second code file "coef_plots_script.R" uses the computed results of the counterfactual impact evaluation to create the final graphic plots using the ggplot2 package.

    The first ".do" file has to be run in STATA, the second one (".R") requires the use of an integrated development environment for R.

    Further Information are avilable in the final report and via the followng URLs:

We assessed CUE using the 18O-labelling method for soils from three European long-term liming field trials (i.e. Jyndevad, Versailles, and Dürnast). Additionally, the immediate response of CUE to liming in the lab was tested accounting for lime-derived CO2 emission. The lime-induced pH shift was a strong determinant of CUE. However, the relationship between CUE and soil pH followed a U-shaped (i.e. quadratic) curve, suggesting that CUE may be lowest at near neutral soil pH and therefore to interfere with agronomic interests (i.e. high crop yield). To assess the potential contribution of CUE on the net liming effect on SOC stocks, we calculated OC inputs and SOC stocks. Liming had a positive effect on SOC stocks, regardless of the change in CUE. Our results suggest that CUE added to the net liming effect on SOC stocks. Statistical analyses and data visualisation were conducted in R v4.1.2 (2021-11-01) (R Core Team, 2020) using RStudio v2022.12.0 (Posit team, 2022).

    Description

    This folder contains the full set of code and data for the CompuCrawl database. The database contains the archived websites of publicly traded North American firms listed in the Compustat database between 1996 and 2020\u2014representing 11,277 firms with 86,303 firm/year observations and 1,617,675 webpages in the final cleaned and selected set.The files are ordered by moment of use in the work flow. For example, the first file in the list is the input file for code files 01 and 02, which create and update the two tracking files "scrapedURLs.csv" and "URLs_1_deeper.csv" and which write HTML files to its folder. "HTML.zip" is the resultant folder, converted to .zip for ease of sharing. Code file 03 then reads this .zip file and is therefore below it in the ordering.The full set of files, in order of use, is as follows:Compustat_2021.xlsx: The input file containing the URLs to be scraped and their date range.01 Collect frontpages.py: Python script scraping the front pages of the list of URLs and generating a list of URLs one page deeper in the domains.URLs_1_deeper.csv: List of URLs one page deeper on the main domains.02 Collect further pages.py: Python script scraping the list of URLs one page deeper in the domains.scrapedURLs.csv: Tracking file containing all URLs that were accessed and their scraping status.HTML.zip: Archived version of the set of individual HTML files.03 Convert HTML to plaintext.py: Python script converting the individual HTML pages to plaintext.TXT_uncleaned.zip: Archived version of the converted yet uncleaned plaintext files.input_categorization_allpages.csv: Input file for classification of pages using GPT according to their HTML title and URL.04 GPT application.py: Python script using OpenAI\u2019s API to classify selected pages according to their HTML title and URL.categorization_applied.csv: Output file containing classification of selected pages.exclusion_list.xlsx: File containing three sheets: 'gvkeys' containing the GVKEYs of duplicate observations (that need to be excluded), 'pages' containing page IDs for pages that should be removed, and 'sentences' containing (sub-)sentences to be removed.05 Clean and select.py: Python script applying data selection and cleaning (including selection based on page category), with setting and decisions described at the top of the script. This script also combined individual pages into one combined observation per GVKEY/year.metadata.csv: Metadata containing information on all processed HTML pages, including those not selected.TXT_cleaned.zip: Archived version of the selected and cleaned plaintext page files. This file serves as input for the word embeddings application.TXT_combined.zip: Archived version of the combined plaintext files at the GVKEY/year level. This file serves as input for the data description using topic modeling.06 Topic model.R: R script that loads up the combined text data from the folder stored in "TXT_combined.zip", applies further cleaning, and estimates a 125-topic model.TM_125.RData: RData file containing the results of the 125-topic model.loadings125.csv: CSV file containing the loadings for all 125 topics for all GVKEY/year observations that were included in the topic model.125_topprob.xlsx: Overview of top-loading terms for the 125 topic model.07 Word2Vec train and align.py: Python script that loads the plaintext files in the "TXT_cleaned.zip" archive to train a series of Word2Vec models and subsequently align them in order to compare word embeddings across time periods.Word2Vec_models.zip: Archived version of the saved Word2Vec models, both unaligned and aligned.08 Word2Vec work with aligned models.py: Python script which loads the trained Word2Vec models to trace the development of the embeddings for the terms \u201csustainability\u201d and \u201cprofitability\u201d over time.99 Scrape further levels down.py: Python script that can be used to generate a list of unscraped URLs from the pages that themselves were one level deeper than the front page.URLs_2_deeper.csv: CSV file containing unscraped URLs from the pages that themselves were one level deeper than the front page.For those only interested in downloading the final database of texts, the files "HTML.zip", "TXT_uncleaned.zip", "TXT_cleaned.zip", and "TXT_combined.zip" contain the full set of HTML pages, the processed but uncleaned texts, the selected and cleaned texts, and combined and cleaned texts at the GVKEY/year level, respectively.The following webpage contains answers to frequently asked questions: https://haans-mertens.github.io/faq/. More information on the database and the underlying project can be found here: https://haans-mertens.github.io/ and the following article: \u201cThe Internet Never Forgets: A Four-Step Scraping Tutorial, Codebase, and Database for Longitudinal Organizational Website Data\u201d, by Richard F.J.

Description
Replication pack, FSE2018 submission #164:
------------------------------------------
**Working title:** Ecosystem-Level Factors Affecting the Survival of Open-Source Projects: 
A Case Study of the PyPI Ecosystem

**Note:** link to data artifacts is already included in the paper. 
Link to the code will be included in the Camera Ready version as well.


Content description
===================

- **ghd-0.1.0.zip** - the code archive. This code produces the dataset files 
 described below
- **settings.py** - settings template for the code archive.
- **dataset_minimal_Jan_2018.zip** - the minimally sufficient version of the dataset.
 This dataset only includes stats aggregated by the ecosystem (PyPI)
- **dataset_full_Jan_2018.tgz** - full version of the dataset, including project-level
 statistics. It is ~34Gb unpacked. This dataset still doesn't include PyPI packages
 themselves, which take around 2TB.
- **build_model.r, helpers.r** - R files to process the survival data 
  (`survival_data.csv` in **dataset_minimal_Jan_2018.zip**, 
  `common.cache/survival_data.pypi_2008_2017-12_6.csv` in 
  **dataset_full_Jan_2018.tgz**)
- **Interview protocol.pdf** - approximate protocol used for semistructured interviews.
- LICENSE - text of GPL v3, under which this dataset is published
- INSTALL.md - replication guide (~2 pages)
Replication guide
=================

Step 0 - prerequisites
----------------------

- Unix-compatible OS (Linux or OS X)
- Python interpreter (2.7 was used; Python 3 compatibility is highly likely)
- R 3.4 or higher (3.4.4 was used, 3.2 is known to be incompatible)

Depending on detalization level (see Step 2 for more details):
- up to 2Tb of disk space (see Step 2 detalization levels)
- at least 16Gb of RAM (64 preferable)
- few hours to few month of processing time

Step 1 - software
----------------

- unpack **ghd-0.1.0.zip**, or clone from gitlab:

   git clone https://gitlab.com/user2589/ghd.git
   git checkout 0.1.0
 
 `cd` into the extracted folder. 
 All commands below assume it as a current directory.
  
- copy `settings.py` into the extracted folder. Edit the file:
  * set `DATASET_PATH` to some newly created folder path
  * add at least one GitHub API token to `SCRAPER_GITHUB_API_TOKENS` 
- install docker. For Ubuntu Linux, the command is 
  `sudo apt-get install docker-compose`
- install libarchive and headers: `sudo apt-get install libarchive-dev`
- (optional) to replicate on NPM, install yajl: `sudo apt-get install yajl-tools`
 Without this dependency, you might get an error on the next step, 
 but it's safe to ignore.
- install Python libraries: `pip install --user -r requirements.txt` . 
- disable all APIs except GitHub (Bitbucket and Gitlab support were
 not yet implemented when this study was in progress): edit
 `scraper/init.py`, comment out everything except GitHub support
 in `PROVIDERS`.

Step 2 - obtaining the dataset
-----------------------------

The ultimate goal of this step is to get output of the Python function 
`common.utils.survival_data()` and save it into a CSV file:

  # copy and paste into a Python console
  from common import utils
  survival_data = utils.survival_data('pypi', '2008', smoothing=6)
  survival_data.to_csv('survival_data.csv')

Since full replication will take several months, here are some ways to speedup
the process:

####Option 2.a, difficulty level: easiest

Just use the precomputed data. Step 1 is not necessary under this scenario.

- extract **dataset_minimal_Jan_2018.zip**
- get `survival_data.csv`, go to the next step

####Option 2.b, difficulty level: easy

Use precomputed longitudinal feature values to build the final table.
The whole process will take 15..30 minutes.
