Highest posterior density hpd interval
Web11 de jun. de 2015 · Bayesian highest posterior density (HPD) intervals can be estimated directly from simulations via empirical shortest intervals. Unfortunately, these can be noisy (that is, have a high Monte Carlo error). We derive an optimal weighting strategy using bootstrap and quadratic programming to obtain a more computationally stable HPD, or in … WebhighestDensityInterval.Rd This function calculates highest density intervals (HDIs) for a given univariate vector. 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. highestDensityInterval(dataVector, alpha, coda =FALSE,
Highest posterior density hpd interval
Did you know?
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.
