TOOL FOR STATISTICS AND PROBABILITY THEORY. --------------------------- Features --------------------------- - Distribution tool - Statistical tests - Descriptives Besides 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 Zipf Continuous 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
