I am finding that I need to refer often to various statistical distributions on Wikipedia. Since Wikipedia is open source, I can re-use their content here. So here are some of my favorite statistical distributions.

Some composite distributions involving the beta distribution are

Beta negative binomial distribution.A closely related distribution is

Inverse beta distribution.There is an application where I needed the moment generating function of the beta distribution. Here it is.

A closely related distribution is the noncentral chi-square distribution.

This distribution has two forms.

A closely related distribuiton is the noncentral F distribution.

This distribution has two forms.

A closely related distribution is the Inverse Gamma distribution.

**Negative binomial distribution.**

Faming Liang, a Professor of Statistics at Texas A&M Univeristy, has some nicely written course notes in PDF format on various distributions as part of his handouts for the STAT 610 course. This includes a derivation of the link between the cumulative probability of a Poisson random variable and percentiles from the Gamma distribution.
