    About this dataset

    Context

    The dataset tabulates the population of Gratis by gender, including both male and female populations. This dataset can be utilized to understand the population distribution of Gratis across both sexes and to determine which sex constitutes the majority.

    Key observations

    There is a slight majority of female population, with 50.0% of total population being female. Source: U.S. Census Bureau American Community Survey (ACS) 2019-2023 5-Year Estimates.

    Content

    When available, the data consists of estimates from the U.S. Census Bureau American Community Survey (ACS) 2019-2023 5-Year Estimates.

    Scope of gender :

    Please note that American Community Survey asks a question about the respondents current sex, but not about gender, sexual orientation, or sex at birth. The question is intended to capture data for biological sex, not gender. Respondents are supposed to respond with the answer as either of Male or Female. Our research and this dataset mirrors the data reported as Male and Female for gender distribution analysis. No further analysis is done on the data reported from the Census Bureau.

    Variables / Data Columns

    • Gender: This column displays the Gender (Male / Female)
    • Population: The population of the gender in the Gratis is shown in this column.
    • % of Total Population: This column displays the percentage distribution of each gender as a proportion of Gratis total population. Please note that the sum of all percentages may not equal one due to rounding of values.

    Description

    Hydrographic and Impairment Statistics (HIS) is a National Park Service (NPS) Water Resources Division (WRD) project established to track certain goals created in response to the Government Performance and Results Act of 1993 (GPRA). One water resources management goal established by the Department of the Interior under GRPA requires NPS to track the percent of its managed surface waters that are meeting Clean Water Act (CWA) water quality standards. This goal requires an accurate inventory that spatially quantifies the surface water hydrography that each bureau manages and a procedure to determine and track which waterbodies are or are not meeting water quality standards as outlined by Section 303(d) of the CWA. This project helps meet this DOI GRPA goal by inventorying and monitoring in a geographic information system for the NPS: (1) CWA 303(d) quality impaired waters and causes; and (2) hydrographic statistics based on the United States Geological Survey (USGS) National Hydrography Dataset (NHD). Hydrographic and 303(d) impairment statistics were evaluated based on a combination of 1:24,000 (NHD) and finer scale data (frequently provided by state GIS layers).

    Description

    Home Value Insights: A Beginner's Regression Dataset

    This dataset is designed for beginners to practice regression problems, particularly in the context of predicting house prices. It contains 1000 rows, with each row representing a house and various attributes that influence its price. The dataset is well-suited for learning basic to intermediate-level regression modeling techniques.

    Features:

    1. Square_Footage: The size of the house in square feet. Larger homes typically have higher prices.
    2. Num_Bedrooms: The number of bedrooms in the house. More bedrooms generally increase the value of a home.
    3. Num_Bathrooms: The number of bathrooms in the house. Houses with more bathrooms are typically priced higher.
    4. Year_Built: The year the house was built. Older houses may be priced lower due to wear and tear.
    5. Lot_Size: The size of the lot the house is built on, measured in acres. Larger lots tend to add value to a property.
    6. Garage_Size: The number of cars that can fit in the garage. Houses with larger garages are usually more expensive.
    7. Neighborhood_Quality: A rating of the neighborhood’s quality on a scale of 1-10, where 10 indicates a high-quality neighborhood. Better neighborhoods usually command higher prices.
    8. House_Price (Target Variable): The price of the house, which is the dependent variable you aim to predict.

    Potential Uses:

    1. Beginner Regression Projects: This dataset can be used to practice building regression models such as Linear Regression, Decision Trees, or Random Forests. The target variable (house price) is continuous, making this an ideal problem for supervised learning techniques.

    2. Feature Engineering Practice: Learners can create new features by combining existing ones, such as the price per square foot or age of the house, providing an opportunity to experiment with feature transformations.

    3. Exploratory Data Analysis (EDA): You can explore how different features (e.g., square footage, number of bedrooms) correlate with the target variable, making it a great dataset for learning about data visualization and summary statistics.

    4. Model Evaluation: The dataset allows for various model evaluation techniques such as cross-validation, R-squared, and Mean Absolute Error (MAE). These metrics can be used to compare the effectiveness of different models.

    Versatility:

    • The dataset is highly versatile for a range of machine learning tasks. You can apply simple linear models to predict house prices based on one or two features, or use more complex models like Random Forest or Gradient Boosting Machines to understand interactions between variables.

    • It can also be used for dimensionality reduction techniques like PCA or to practice handling categorical variables (e.g., neighborhood quality) through encoding techniques like one-hot encoding.

    • This dataset is ideal for anyone wanting to gain practical experience in building regression models while working with real-world features.

    Overview:

    This dataset provides a unique resource for researchers and data scientists interested in the global dynamics of the COVID-19 pandemic. It focuses on the impact of different SARS-CoV-2 variants and mutations on the duration of local epidemics. By combining variant information with epidemiological data, this dataset allows for a comprehensive analysis of factors influencing the trajectory of the pandemic.

    Key Features:

    • Global Coverage: Includes data from multiple countries.
    • Variant-Specific Information: Detailed records for various SARS-CoV-2 variants.
    • Epidemic Duration: Data on the duration of local epidemics, accounting for right-censoring.
    • Epidemiological Variables: Includes mortality rates, a proxy for R0, transmission proxies, and other pertinent variables.
    • Geographical characteristics: Include a continent variable for exploring geographical patterns
    • Time varying variables: Include the number of waves and the number of variants in the different countries for more in-depth exploration.

    Data Source: The data combines information from the Johns Hopkins University COVID-19 dataset (confirmed_cases.csv and deaths_cases.csv) and the covariants.org dataset (variants.csv). The dataset you see here is the combination of two datasets from Johns Hopkins University and covariants.org.

    Questions to Inspire Users:

    This dataset is designed for a diverse set of analytical questions. Here are some ideas to inspire the Kaggle community:

    Survival Analysis:

    1. How do different SARS-CoV-2 variants influence the duration of local epidemics?
    2. Which factors (mortality, R0, etc.) are most strongly associated with shorter or longer epidemic durations?
    3. Does the type of variant/mutation (mutation,S, Omicron, Delta, Other) have a significant impact on epidemic duration?
    4. Is there a geographical pattern to the duration of epidemics?

    Epidemiological Analysis:

    1. How do local transmission rates (represented by our proxy of R0) affect the duration of an epidemic?
    2. Do countries with higher mortality rates have different patterns of epidemic progression?
    3. How can we predict the duration of an epidemic based on its initial characteristics?
    4. How does the number of epidemic waves impact the duration of an epidemic?
    5. Does the number of variants in a country affect the duration of an épidémie?

    Data Science/Machine Learning:

    1. Can we develop a machine learning model to predict the duration of an epidemic?
    2. What features have the best predictive power ?
    3. Can we identify clusters of variants/regions with similar epidemic patterns?
    4. Are there interactions between variables that can explain the non-linearities that we have identified ?

    Description

    Coups d'Ètat are important events in the life of a country. They constitute an important subset of irregular transfers of political power that can have significant and enduring consequences for national well-being. There are only a limited number of datasets available to study these events (Powell and Thyne 2011, Marshall and Marshall 2019). Seeking to facilitate research on post-WWII coups by compiling a more comprehensive list and categorization of these events, the Cline Center for Advanced Social Research (previously the Cline Center for Democracy) initiated the Coup d’État Project as part of its Societal Infrastructures and Development (SID) project. More specifically, this dataset identifies the outcomes of coup events (i.e., realized, unrealized, or conspiracy) the type of actor(s) who initiated the coup (i.e., military, rebels, etc.), as well as the fate of the deposed leader. Version 2.1.3 adds 19 additional coup events to the data set, corrects the date of a coup in Tunisia, and reclassifies an attempted coup in Brazil in December 2022 to a conspiracy. Version 2.1.2 added 6 additional coup events that occurred in 2022 and updated the coding of an attempted coup event in Kazakhstan in January 2022. Version 2.1.1 corrected a mistake in version 2.1.0, where the designation of “dissident coup” had been dropped in error for coup_id: 00201062021. Version 2.1.1 fixed this omission by marking the case as both a dissident coup and an auto-coup. Version 2.1.0 added 36 cases to the data set and removed two cases from the v2.0.0 data. This update also added actor coding for 46 coup events and added executive outcomes to 18 events from version 2.0.0. A few other changes were made to correct inconsistencies in the coup ID variable and the date of the event. Version 2.0.0 improved several aspects of the previous version (v1.0.0) and incorporated additional source material to include: • Reconciling missing event data • Removing events with irreconcilable event dates • Removing events with insufficient sourcing (each event needs at least two sources) • Removing events that were inaccurately coded as coup events • Removing variables that fell below the threshold of inter-coder reliability required by the project • Removing the spreadsheet ‘CoupInventory.xls’ because of inadequate attribution and citations in the event summaries • Extending the period covered from 1945-2005 to 1945-2019 • Adding events from Powell and Thyne’s Coup Data (Powell and Thyne, 2011)

    Description

    This training dataset was calculated using the mechanistic modeling approach. See “Big data training data for artificial intelligence-based Li-ion diagnosis and prognosis“ (Journal of Power Sources, Volume 479, 15 December 2020, 228806) and "Analysis of Synthetic Voltage vs. Capacity Datasets for Big Data Diagnosis and Prognosis" (Energies, under review) for more details

    The V vs. Q dataset was compiled with a resolution of 0.01 for the triplets and C/25 charges. This accounts for more than 5,000 different paths. Each path was simulated with at most 0.85% increases for each The training dataset, therefore, contains more than 700,000 unique voltage vs. capacity curves.

    4 Variables are included, see read me file for details and example how to use. Cell info: Contains information on the setup of the mechanistic model Qnorm: normalize capacity scale for all voltage curves pathinfo: index for simulated conditions for all voltage curves volt: voltage data. Each column corresponds to the voltage simulated under the conditions of the corresponding line in pathinfo.

    Description

    The Calls for Service dataset includes police service requests for which patrol officers, traffic officers, bike officers and, on occasion, detectives will be dispatched to public safety response. It also includes self-initiated calls for service where an officer witnesses a violation or suspicious activity for which they would respond. This item represents a consolidated item of all records.Why the Datasets are Organized into Separate Layers In January of 2022, the Tempe Police Department completed a major transition in how crimes data is reported, moving from the FBI Uniform Crime Report program to the enhanced National-Incident Based Reporting System, or NIBRS. NIBRS is now the required reporting method for the FBI. The Uniform Crime Report (UCR) Program's traditional Summary Reporting System (SRS) was limited in comparison to NIBRS, which offers more detailed data collection that provides a deeper understanding of crime and its circumstances. NIBRS captures a wider range of details on crime incidents and can reflect separate offenses occurring during the same event, including information on victims, known offenders, relationships between victims and offenders, arrestees, and property involved in the crimes. With greater specificity in reporting offenses, NIBRS provides for more accurate and detailed crime-related information, and helps give context to specific crime issues while affording greater analytic capability of crime. Below is the link to Tempe-specific NIBRS reports. Use the drop-down filters to select Tempe PD, the year, and the type of report. Because of these differences, trends and numbers between the two systems should not be directly compared. That’s why we treat 2022 and later (NIBRS) separately from 2021 and earlier (UCR). To make the older data easier to browse, we grouped the data from 2021 and earlier into year ranges instead of showing it all at once. This helps with performance and loading speed due to the large count of records. For detailed guidance on interpreting calls for service data, as well as data scope and limitations, please refer to the User Guide.Data DictionaryAdditional InformationContact Email: PD_DataRequest@tempe.govContact Phone: N/ALink: N/AData Source: Versaterm Informix RMSData Source Type: Informix and/or SQL ServerPreparation Method: Automated processPublish Frequency: DailyPublish Method: Automatic
