Highest posterior density hpd interval

WebHighest-posterior density (HPD) intervals (recommended, for example, in the classic book of Box and Tiao, 1973) are easily determined for models with closed-form distributions such as the nor-mal and gamma but are more di cult to compute from simulations. WebThese functions compute the highest posterior density intervals (sometimes called minimum length confidence intervals) for a Bayesian posterior distribution. The hpd function is used when you have a function representing the inverse cdf (the common case with conjugate families).
