WebThis function calculates highest density intervals (HDIs) for a given univariate vector. Typically, this is done to obtain highest posterior density (HPD) for each freely varying parameter estimated in the posterior of a Bayesian MCMC analysis. If these intervals are calculated for more than one variable, they are referred to instead as regions.
