Smartphone Probability Distribution Applications

Created by Professor Matt Bognar at University of Iowa.

Probability Distributions (iOS, Android)
This is a free probability distribution application for iOS and Android. It computes probabilities and quantiles for the binomial, geometric, Poisson, negative binomial, hypergeometric, normal, t, chi-square, F, gamma, log-normal, and beta distributions.

More information: iOS , Android.

For both platforms, the *Negative Binomial (II) distribution is relevant for the Montgomery parameterization. The Negative Binomial (I) distribution is for a different parametrization (don't use this other parameterization labeled as I).
