Writes “Weâd need to know the probability one beta distribution is greater than another. This question is not trivial to answer, and Iâm going to illustrate four routes that are common lines of attack in a Bayesian problem: Simulation of posterior draws; Numerical integration; Closed-form solution; and Closed-form approximation”
