Applications of Life Tables01:22

Applications of Life Tables

56
Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...

Systematic Sampling Method01:17

Systematic Sampling Method

10.2K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
Systematic sampling is one of the simplest methods...

Censoring Survival Data01:09

Censoring Survival Data

72
Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different...

The Anderson-Darling Test01:16

The Anderson-Darling Test

691
The Anderson-Darling test is a statistical method used to determine whether a data sample is likely drawn from a specific theoretical distribution. Unlike parametric tests, it does not require assumptions about specific parameters of the distribution. Instead, it compares the sample's empirical cumulative distribution function (ECDF) with the cumulative distribution function (CDF) of the hypothesized distribution. Critical values for the test are specific to the chosen distribution rather...

Stratified Sampling Method

Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a stratified sample, divide the population into groups called strata and then take a...

Wald-Wolfowitz Runs Test I01:17

Wald-Wolfowitz Runs Test I

630
The Wald-Wolfowitz test, also known as the runs test, is a nonparametric statistical test used to assess the randomness of a sequence of two different types of elements (e.g., positive/negative values, successes/failures). It examines whether the order of the elements in a sequence is random or if there is a pattern or trend present. This nonparametric test applies to any ordered data despite the population and sample data distribution, even if a higher sample size is available.
The test works...

Area of Science:

  • Political Science
  • Comparative Politics
  • Electoral Studies

Background:

  • The Democratic Electoral Systems (DES) dataset is a crucial resource for studying electoral processes.
  • Existing DES data covers the post-war period, necessitating an update for earlier historical analysis.
  • Understanding interwar democratic systems requires comprehensive data on electoral institutions and outcomes.

Purpose of the Study:

  • To introduce an updated version of the DES dataset, extending coverage to the interwar period (1919-1945).
  • To provide detailed information on electoral rules and outcomes for legislative and presidential elections.
  • To enhance data utility by including democracy classifications and linkage variables for broader research.

Main Methods:

  • Compilation of data from 243 legislative lower house and presidential elections across 34 interwar democracies.
  • Inclusion of variables detailing institutional rules governing election organization.
  • Integration of summary statistics on electoral outcomes and multiple identification variables for data linkage.

Main Results:

  • The updated DES dataset offers comprehensive coverage of electoral systems in interwar democracies.
  • Data includes institutional rules, electoral outcomes, and democracy classifications from major datasets.
  • The dataset is compatible with previous releases, facilitating longitudinal analysis.

Conclusions:

  • This data update significantly expands the scope of the DES dataset for historical political science research.
  • Researchers can now analyze electoral systems and their consequences in interwar democracies with greater detail.
  • The enhanced dataset supports comparative studies by offering flexible democracy definitions and data linkage capabilities.
