Despite recent papers on problems associated with full-model and stepwise regression, their use is still common throughout ecological and environmental disciplines. Alternative approaches, including generating multiple models and comparing them post-hoc using techniques such as Akaike's Information Criterion (AIC), are becoming more popular. However, these are problematic when there are numerous independent variables and interpretation is often difficult when competing models contain many different variables and combinations of variables. Here, we detail a new approach, REVS (Regression with Empirical Variable Selection), which uses all-subsets regression to quantify empirical support for every independent variable. A series of models is created; the first containing the variable with most empirical support, the second containing the first variable and the next most-supported, and so on. The comparatively small number of resultant models (n = the number of predictor variables) means that post-hoc comparison is comparatively quick and easy. When tested on a real dataset – habitat and offspring quality in the great tit (Parus major) – the optimal REVS model explained more variance (higher R2), was more parsimonious (lower AIC), and had greater significance (lower P values), than full, stepwise or all-subsets models; it also had higher predictive accuracy based on split-sample validation. Testing REVS on ten further datasets suggested that this is typical, with R2 values being higher than full or stepwise models (mean improvement = 31% and 7%, respectively). Results are ecologically intuitive as even when there are several competing models, they share a set of “core” variables and differ only in presence/absence of one or two additional variables. We conclude that REVS is useful for analysing complex datasets, including those in ecology and environmental disciplines.

This dataset provides geospatial location data and scripts used to analyze the relationship between MODIS-derived NDVI and solar and sensor angles in a pinyon-juniper ecosystem in Grand Canyon National Park. The data are provided in support of the following publication: "Solar and sensor geometry, not vegetation response, drive satellite NDVI phenology in widespread ecosystems of the western United States". The data and scripts allow users to replicate, test, or further explore results. The file GrcaScpnModisCellCenters.csv contains locations (latitude-longitude) of all the 250-m MODIS (MOD09GQ) cell centers associated with the Grand Canyon pinyon-juniper ecosystem that the Southern Colorado Plateau Network (SCPN) is monitoring through its land surface phenology and integrated upland monitoring programs. The file SolarSensorAngles.csv contains MODIS angle measurements for the pixel at the phenocam location plus a random 100 point subset of pixels within the GRCA-PJ ecosystem. The script files (folder: 'Code') consist of 1) a Google Earth Engine (GEE) script used to download MODIS data through the GEE javascript interface, and 2) a script used to calculate derived variables and to test relationships between solar and sensor angles and NDVI using the statistical software package 'R'. The file Fig_8_NdviSolarSensor.JPG shows NDVI dependence on solar and sensor geometry demonstrated for both a single pixel/year and for multiple pixels over time. (Left) MODIS NDVI versus solar-to-sensor angle for the Grand Canyon phenocam location in 2018, the year for which there is corresponding phenocam data. (Right) Modeled r-squared values by year for 100 randomly selected MODIS pixels in the SCPN-monitored Grand Canyon pinyon-juniper ecosystem. The model for forward-scatter MODIS-NDVI is log(NDVI) ~ solar-to-sensor angle. The model for back-scatter MODIS-NDVI is log(NDVI) ~ solar-to-sensor angle + sensor zenith angle. Boxplots show interquartile ranges; whiskers extend to 10th and 90th percentiles. The horizontal line marking the average median value for forward-scatter r-squared (0.835) is nearly indistinguishable from the back-scatter line (0.833). The dataset folder also includes supplemental R-project and packrat files that allow the user to apply the workflow by opening a project that will use the same package versions used in this study (eg, .folders Rproj.user, and packrat, and files .RData, and PhenocamPR.Rproj). The empty folder GEE_DataAngles is included so that the user can save the data files from the Google Earth Engine scripts to this location, where they can then be incorporated into the r-processing scripts without needing to change folder names. To successfully use the packrat information to replicate the exact processing steps that were used, the user should refer to packrat documentation available at https://cran.r-project.org/web/packages/packrat/index.html and at https://www.rdocumentation.org/packages/packrat/versions/0.5.0. Alternatively, the user may also use the descriptive documentation phenopix package documentation, and description/references provided in the associated journal article to process the data to achieve the same results using newer packages or other software programs.

This is a clean subset of the data that was created by the OpenML R Bot that executed benchmark experiments on binary classification task of the OpenML100 benchmarking suite with six R algorithms: glmnet, rpart, kknn, svm, ranger and xgboost. The hyperparameters of these algorithms were drawn randomly. In total it contains more than 2.6 million benchmark experiments and can be used by other researchers. The subset was created by taking 500000 results of each learner (except of kknn for which only 1140 results are available). The csv-file for each learner is a table that for each benchmark experiment has a row that contains: OpenML-Data ID, hyperparameter values, performance measures (AUC, accuracy, brier score), runtime, scimark (runtime reference of the machine), and some meta features of the dataset.OpenMLRandomBotResults.RData (format for R) contains all data in seperate tables for the results, the hyperparameters, the meta features, the runtime, the scimark results and reference results.

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.

This dataset is a subset of the CODE 15% dataset obtained by random sampling from the negative class while maintaining all the observations of the positive class to create a balanced dataset without the need to focus on class imbalance.

The code15_hdf5 folder contains the exams and labels for the entire CODE 15% dataset. The code15_wfdb folder contains the exam records file in .dat format.

An additional file (signals_features.csv) is provided, containing handcrafted features from the ECG records (lead II) related to P, Q, R, S, and T waves. Features such as P wave duration, PR interval, PR segment, QRS duration, ST segment, and ST slope were computed by first extracting all the points using the neurokit2 Python library and then aggregated for each record ID using descriptive statistics. Heart rate variability features were also included along with the P, Q, R, S, and T waves.

This dataset is provided in support of the following publication: "Solar and sensor geometry, not vegetation response, drive satellite NDVI phenology in widespread ecosystems of the western United States". The data and code provided allow users to replicate, test, or further explore results. The dataset includes 2 raster datasets (folder:Rasters): 1) 'cntWinterPks2003_2018DR' provides a count of years with winter peaks from 2003-2018 in an 11-state area in the western United States. 2) 'VegClassGte5_2003_2018' raster, within the zip file 'WinterPeaksVegTypes.zip' identifies the broad vegetation types for locations with common winter peaks (5 or more years out of 16). The dataset also includes Google Earth Engine and R code files used to create the datasets. Additional files/folders provided include 1) Google Earth Engine scripts used to download MODIS data the GEE - javascript interface (folder: 'Code'). 2) Scripts used to manipulate rasters and to calculate and map the occurrence winter NDVI peaks from 2003-2018 using the statistical software package 'R'. 3) Supplemental R-project and packrat files that allow the user to apply the workflow by opening a project that will use the same package versions used in this study, for example the folders 'Rproj.user', and 'packrat', and files '.RData', and 'WinterPeakExtentPR.Rproj'. 4) Empty folders ('GEE_DataAnnPeak', 'GEE_DataLoose', and 'GEE_DataStrict') that should be used to contain the output from the GEE code files as follows: 'GEE_DataAnnPeak' should contain output from the S3 and S4 scripts, 'GEE_DataLoose' should contain output from the S1 script, and 'GEE_DataStrict' should contain output from the S2 script. 5) Graphic file 'Fig_9_MapsOfExtentPortrait2.jpg' shows temporal and ecosystem distribution of winter NDVI peaks in the western continental US, 2003 to 2018, derived from MODIS MCD43A4 product. TOP: Number of years with winter peaks in areas that meet defined thresholds for biomass (median annual peak NDVI >= 0.15) and temperature (mean December minimum daily temperature <= 0°C). BOTTOM: Predominant LANDFIRE Existing Vegetation Type physiognomy (i.e., mode of each 500-m MODIS pixel) in areas with >= 5 years of winter peaks. Present in lesser proportions but not identified on the map for legibility reasons are conifer-hardwood, exotics, riparian, and sparsely vegetated physiognomic categories as well as non-natural/non-terrestrial ecosystem categories. State abbreviations are AZ (Arizona), CA (California), CO (Colorado), ID (Idaho), MT (Montana), NV (Nevada), NM (New Mexico), OR (Oregon), WA (Washington), and WY (Wyoming). The final steps of overlaying common winter peak extent data on the Landfire data were done using ArcGIS and the publicly available Landfire dataset (see source datasets section of metadata and process steps). To successfully use the packrat information to replicate the exact processing steps that were used, the user should refer to packrat documentation available at https://cran.r-project.org/web/packages/packrat/index.html and at https://www.rdocumentation.org/packages/packrat/versions/0.5.0.

This dataset provides calculated camera-NDVI data for individual regions-of-interest (ROI's) for the phenocam named 'GRCA1PJ' (part of the Phenocam Network, https://phenocam.sr.unh.edu/webcam/). The GRCA1PJ phenocam is within a pinyon-juniper woodland in Grand Canyon National Park. Camera-NDVI refers to a modified version of NDVI calculated by the phenopix package (Filippa et al., 2016). The camera-calculated NDVI data are in the folder FinalOutput. File attributes within that folder are described in detail in the entity and attribute information section of this metadata. It should be possible for the user to use only the ROI definitions, image data downloaded from the phenocam network, and the phenopix R-package to reproduce the final NDVI dataset. However, the dataset also contains scripts and intermediate files that may be helpful in reproducing or extending the processing, but are not essential to reproducing the data. The complete dataset release includes 1) A workflow spreadsheet file that describes the processing steps, associated scripts, and output filenames (filename:Workflow_With_Filenames.ods). 2) R-code script files used in processing (folder:'Code'). 3) ROI boundary files and jpg images for the ROIs presented in the linked publication. (folder:"Phenocamdata/grca1pj/ROI") 4) Ancillary files used to create the NDVI dataset; these include exposure coordinates and training files (folder:'Phenocamdata/grca1pj/Ancillary'). 5) Files listing exposures for individual photos within the initial processing time period (folder:'Exposures'). 6) Screening parameters for cloud and poor-light-condition screening of photos, as well as a list of photos that meet the cloud-screening standards (folder:'Phenocamdata/grca1pj/BlueSkyScreening'). 7) Vegetation index files produced by the phenopix package, organized by ROI and month-year group (folder:"Phenocamdata/grca1pj/VI_Tables"). 8) Supplemental R-project and packrat files that allow the user to apply the workflow by opening a project that will use the same package versions used in this study (eg, .folders Rproj.user, and packrat, and files .RData, and PhenocamPR.Rproj). 9) The graphic 'Fig_4_ROIWithLabels.jpg' shows the phenocam field of view with labelled ROIs. outline colors correspond to juniper (red), pinyon (blue), 238 and other species (yellow). Labels correspond to NDVI curves in 'Fig_7_PhenocamCurves.JPG', (also included in this data release). The composite area comprises the field of view beneath the approximate horizon line labelled ‘J’ (gray). This image corresponds to Figure 4 in the associated journal article. 10) The graphic 'Fig_7_PhenocamCurves.JPG' shows NDVI curves derived from phenocam images from September 2017 - December 2018 for individual regions of interest (ROIs). Letter designations correspond to ROI labels in Fig_4_ROIWithLabels.jpg (also included in this data release). Data were screened to remove cloudy photos during Aqua and Terra flyover hours. Black ellipses indicate times when the ROI target vegetation was shaded. Red ellipses indicate times when the background of the ROI was shaded. To improve visibility, the Y axis is restricted and excludes 37 extreme values out of a total of 6698 values. The exposure adjustment method used by the phenopix package produces NDVI values that have a strong linear correlation with spectroradiometer-derived NDVI but are negatively shifted so that vegetated areas often have NDVI values below zero. This image corresponds to Figure 7 in the associated journal article. The file types .Rdata or .rds are commonly used in this release because these are the types created by the phenopix processing package, and these files will be needed (or the user will need to recreate new versions) for further processing. The scripts enable the user to replicate processing or to extend it to different times or areas of interest; however, these scripts require as additional input phenocam imagery that the user must download. To successfully use the packrat information to replicate the exact processing steps that were used, the user should refer to packrat documentation available at https://cran.r-project.org/web/packages/packrat/index.html and at https://www.rdocumentation.org/packages/packrat/versions/0.5.0. Alternatively, the user may also use the descriptive documentation phenopix package documentation, and description/references provided in the associated journal article to process the data to achieve the same results using newer packages or other software programs. Species-specific phenological curves included in the NDVI output section this dataset: Juniperus osteosperma, Pinus edulis, Purshia stansburiana, Artemisia tridentata, and Chamaebatiaria millefolium

Abstract: These are results from a network of 65 tree census plots in Panama. At each, every individual stem in a rectangular area of specified size is given a unique number and identified to species, then stem diameter measured in one or more censuses. Data from these numerous plots and inventories were collected following the same methods as, and species identity harmonized with, the 50-ha long-term tree census at Barro Colorado Island. Precise location of every site, elevation, and estimated rainfall (for many sites) are also included. These data were gathered over many years, starting in 1994 and continuing to the present, by principal investigators R. Condit, R. Perez, S. Lao, and S. Aguilar. Funding has been provided by many organizations.Description:marenaRecent.full.Rdata5Jan2013.zip: A zip archive holding one R Analytical Table, a version of the Marena plots' census data in R format, designed for data analysis. This and all other tables labelled 'full' have one record per individual tree found in that census. Detailed documentations of the 'full' tables is given in RoutputFull.pdf (see component 10 below); an additional column 'plot' is included because the table includes records from many different locations. Plot coordinates are given in PanamaPlot.txt (component 12 below). This one file, 'marenaRecent.full1.rdata', has data from the latest census at 60 different plots. These are the best data to use if only a single plot census is needed. marena2cns.full.Rdata5Jan2013.zip: R Analytical Tables of the style 'full' for 44 plots with two censuses: 'marena2cns.full1.rdata' for the first census and 'marena2cns.full2.rdata' for the second census. These 44 plots are a subset of the 60 found in marenaRecent.full (component 1): the 44 that have been censused two or more times. These are the best data to use if two plot censuses are needed. marena3cns.full.Rdata5Jan2013.zip. R Analytical Tables of the style 'full' for nine plots with three censuses: 'marena3cns.full1.rdata' for the first census through 'marena2cns.full3.rdata' for the third census. These nine plots are a subset of the 44 found in marena2cns.full (component 2): the nine that have been censused three or more times. These are the best data to use if three plot censuses are needed. marena4cns.full.Rdata5Jan2013.zip. R Analytical Tables of the style 'full' for six plots with four censuses: 'marena4cns.full1.rdata' for the first census through 'marena4cns.full4.rdata' for the fourth census. These six plots are a subset of the nine found in marena3cns.full (component 3): the six that have been censused four or more times. These are the best data to use if four plot censuses are needed. marenaRecent.stem.Rdata5Jan2013.zip. A zip archive holding one R Analytical Table, a version of the Marena plots' census data in R format. These are designed for data analysis. This one file, 'marenaRecent.full1.rdata', has data from the latest census at 60 different plots. The table has one record per individual stem, necessary because some individual trees have more than one stem. Detailed documentations of these tables is given in RoutputFull.pdf (see component 11 below); an additional column 'plot' is included because the table includes records from many different locations. Plot coordinates are given in PanamaPlot.txt (component 12 below). These are the best data to use if only a single plot census is needed, and individual stems are desired. marena2cns.stem.Rdata5Jan2013.zip. R Analytical Tables of the style 'stem' for 44 plots with two censuses: 'marena2cns.stem1.rdata' for the first census and 'marena3cns.stem2.rdata' for the second census. These 44 plots are a subset of the 60 found in marenaRecent.stem (component 1): the 44 that have been censused two or more times. These are the best data to use if two plot censuses are needed, and individual stems are desired. marena3cns.stem.Rdata5Jan2013.zip. R Analytical Tables of the style 'stem' for nine plots with three censuses: 'marena3cns.stem1.rdata' for the first census through 'marena3cns.stem3.rdata' for the third census. These nine plots are a subset of the 44 found in marena2cns.stem (component 6): the nine that have been censused three or more times. These are the best data to use if three plot censuses are needed, and individual stems are desired. marena4cns.stem.Rdata5Jan2013.zip. R Analytical Tables of the style 'stem' for six plots with four censuses: 'marena3cns.stem1.rdata' for the first census through 'marena3cns.stem3.rdata' for the third census. These six plots are a subset of the nine found in marena3cns.stem (component 7): the six that have been censused four or more times. These are the best data to use if four plot censuses are needed, and individual stems are desired. bci.spptable.rdata. A list of the 1414 species found across all tree plots and inventories in Panama, in R format. The column 'sp' in this table is a code identifying the species in the full census tables (marena.full and marena.stem, components 1-4 and 5-8 above). RoutputFull.pdf: Detailed documentation of the 'full' tables in Rdata format (components 1-4 above). RoutputStem.pdf: Detailed documentation of the 'stem' tables in Rdata format (component 5-8 above). PanamaPlot.txt: Locations of all tree plots and inventories in Panama.
