Reading 14a: Beta Distributions - MIT OpenCourseWare
ocw.mit.eduClass 14, 18.05 Jeremy Orlo and Jonathan Bloom 1 Learning Goals 1. Be familiar with the 2-parameter family of beta distributions and its normalization. 2. Be able to update a beta prior to a beta posterior in the case of a binomial likelihood. 2 Beta distribution The beta distribution beta(a;b) is a two-parameter distribution with range [0;1 ...

web.stanford.eduBeta(s+ ;n s+ ), so this Beta distribution is the posterior distribution of P. In the previous example, the parametric form for the prior was (cleverly) chosen so that the posterior would be of the same form|they were both Beta distributions. This type of prior is called a conjugate prior for P in the Bernoulli model. Use of a conjugate prior

This flexibility encourages its empirical use in a wide range of ap-plications” (Johnson, Kotz and Balakrishnan, 1995, p. 235). Several applications of the beta distribution are discussed by Bury (1999) and by Johnson, Kotz and Balakrish-
