WebUnlike Bayesian credible intervals, it is very computationally intensive to compute HPD intervals unless one deals with a simple Bayesian model such as a standard normal model in which one makes inference about the normal mean. Tanner (1996) provided a Monte Carlo algorithm to calculate the content and boundary of the HPD region. WebMar 4, 2024 · For eg: If we say that 95% HPD for some analysis lies between [5 and 8] means that based on our data and model, we think the parameter in question is between 5 and 8 with a probability of 0.95.
