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 … Web29 de jun. de 2024 · Instead, sometimes it can make sense to use a shortest probability interval (similar to the highest posterior density interval), as discussed in this paper with Ying Liu and Tian Zheng.

R: Compute Highest Posterior Density Intervals

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. WebAnother frequently used Bayesian credible set is called the highest posterior density (HPD) interval. A HPD interval is a region that satisfies the following two conditions: The posterior probability of that region is . The minimum density of any point within that region is equal to or larger than the density of any point outside that region.
