STA: Statistical Toolbox

TOOL FOR STATISTICS AND PROBABILITY THEORY.---------------------------Features---------------------------- Distribution tool- Statistical tests- DescriptivesBesides these areas, the application supports saving, loading, and deleting datasets where applicable.---------------------------Distribution tool---------------------------The distribution tool offers the following features: plot the pdf/pmf, properties (like mean value, variance, and support), cumulative probability, point mass/density, quantiles, and generating/sampling from the distribution.Discrete probability distributions: Binomial, Hypergeometric, Negative binomial (or Pascal as it is also called), Poisson, uniform, and ZipfContinuous probability distributions: Beta, Cauchy, Chi^2 (Chi squarred), Exponential, F (or Fisher-Snedecor as it is also called), Gamma, Normal (or Gaussian as it is also called), Student's t, uniform, and Weibull---------------------------Statistical tests---------------------------- One way ANOVA- Chi^2 tests: Pearson's Chi^2 test for independence and observed vs expected counts- Correlation tests: Pearson's correlation and Spearman's correlation- Student's t-tests: One sample and two sample (both homoscedastic and heteroscedastic are supported)---------------------------Descriptives---------------------------- Plot a histogram- Summary statistics as: number of observations, min, max, mean, standard deviation, variance, median, skewness, and kurtosis
