WebHá 2 dias · Decision-theoretic interval estimation requires the use of loss functions that, typically, take into account the size and the coverage of the sets. We here consider the class of monotone loss functions that, under quite general conditions, guarantee Bayesian optimality of highest posterior probability sets. We focus on three specific families of … WebThe posterior distribution is therefore Gamma(α + Σxi, n + β). To find the 95 percent HPD interval, we need to find the interval that contains 95 percent of the posterior probability density with the highest density. This is the shortest interval that includes the point estimate of λ and has a total probability of 0.95. WebHDInterval: Highest (Posterior) Density Intervals.
