summarize_beta_binomial {bayesrules} | R Documentation |
Consider a Beta-Binomial Bayesian model for parameter \pi
with
a Beta(alpha, beta) prior on \pi
and Binomial likelihood with n trials
and y successes. Given information on the prior (alpha and data) and data (y and n),
this function summarizes the mean, mode, and variance of the
prior and posterior Beta models of \pi
.
