21 Distributions

The parameterizations and notations for distributions largely follow A. Gelman, Carlin, et al. (2013) and Stan Development Team (2016).

The Wikipedia List of Probability Distributions is a fairly complete reference. Standard references of probability distributions are (Johnson, Kotz, and Balakrishnan 1994, 1995, 1997; Kotz, Balakrishnan, and Johnson 2000; Wimmer and Altmann 1999; Forbes et al. 2010; Asquith 2011).

The Probability Distributions CRAN task view contains both links and descriptions of probability distributions and as such serves as a useful list of probability distributions.

“The Chart of Univariate Distribution Relationships” (Leemis and McQueston 2008) is the classic chart of the relationships between univariate distributions.

There are a few variations of this chart online:

• Univariate Distribution Relationships
• Diagram of distribution relationships
• ProbOnto
