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

- Summary statistics as: number of observations, min, max, mean, standard deviation, variance, median, skewness, and kurtosis

Recent changes:

General:

- Ads removed

- Apache Commons Math updated to 3.2

Bugs fixed:

- Problems with discrete random samples fixed
