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 … WebCompute the Highest Density Interval (HDI) of posterior distributions. All points within this interval have a higher probability density than points outside the interval. The HDI can be used in the context of uncertainty characterisation of posterior distributions as Credible Interval (CI). Usage hdi(x, ...)

hpd : Compute Highest Posterior Density Intervals

WebRaw Blame. function hpdi = hpdi (x, p) % HPDI - Estimates the Bayesian HPD intervals. %. % Y = HPDI (X,P) returns a Highest Posterior Density (HPD) interval. % for each column of X. P must be a scalar. Y is a 2 row matrix. % where ith column is HPDI for ith column of X. 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). WebA highest posterior density ( HPD) region of confidence level α α is a (1−α) ( 1 − α) -confidence region I α I α for which holds that the posterior density for every point in this set is higher than the posterior density … list of fatal diseases
