Web27 apr 2015 · HPD is one of the methods for defining a credible interval in Bayesian statistics. A credible interval is an interval within which an unobserved parameter value falls with a particular probability. It is an interval in the domain of a posterior probability distribution or a predictive distribution. Web31 lug 2024 · In a Bayesian context, to analyse the posterior distribution, one can define the Highest Posterior Density (HPD) region or interval as $$\{\theta; \pi(\theta \mid x) \geq k\} $$ in both unidimensional and multidimensional case (Robert - The Bayesian Choice, p 25).In the unidimensional case, the HPD region is an interval or an union of intervals.
