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

It's an awesome app, though i'd love better graphing since it's very limited.
[2011-03-24] Paul:
Awesome! Can't believe it's free! Development wish list would be to include Weibull B10 calls for reliability, but I still use this a lot.

Amazing!!!
[2011-03-05] Ananda:
Awesome app! Like having all the stats tables in my pocket. UI could use a little more polish.
