STA: Statistical Toolbox

STA: Statistical Toolbox


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

Needs own keyboard Very unwieldy because, with TouchPal keyboard, have to manually go back to numbers after every entry. Fix this and it looks good.
