Probabilities is a collection of mathematical functions and statistical distributions. It includes probability density function (PDF), cumulative distribution function (CDF) and point percent function (PPF) for 40 different statistical distributions. The following statistical distributions are supported: Beta, Bose-Einstein, Cauchy, Chi-Squared , Erlang, Exponential distribution, Fatigue life, Fermi-Dirac, Fisher (F) , GEV, Generalized Pareto, Gamma, Gumbel minimum or maximum, Inverse Chi-Squared, Inverse Gaussian, Johnson bounded or unbounded, Laplace, Logistic, Log-normal, Log-Weibull , Maxwell , Normal, Pareto, Power, Rayleigh, Student (T), Triangular, Uniform, Weibull distribution. Also, the following discrete distributions are supported: Bernoulli, Binomial, Geometric, Hypergeometric, Logarithmic, Negative binomial, Poisson, Discrete uniform, Zipf distribution. In addition, the package includes many basic math functions with full complex number support. For fast calculation, all the math functions are written in assembler.
