WebAug 18, 2024 · The beta distribution is often used as a Bayesian conjugate prior for a binomial likelihood. It is often explained with the example that ( α − 1) is analogous to the number of successes and ( β − 1) is like the number of fails. As expected, a beta distribution with α = β = 1 is equivalent to a uniform distribution.
