WebMCMC: Metropolis Hastings Algorithm A good reference is Chib and Greenberg (The American Statistician 1995). Recall that the key object in Bayesian econometrics is the posterior distribution: f(YT jµ)p(µ) p(µjYT) = f(Y ~ T jµ)dµ~ It is often di–cult to compute this distribution. In particular, R the integral in the denominator is di–cult. WebMay 9, 2024 · Metropolis Hastings is a MCMC (Markov Chain Monte Carlo) class of sampling algorithms. Its most common usage is optimizing sampling from a posterior distribution when the analytical form is intractable or implausible to sample. This post follows the Statistics and the historical steps that led to the appearance of this algorithm.
In statistics and statistical physics, the Metropolis–Hastings algorithm is a Markov chain Monte Carlo (MCMC) method for obtaining a sequence of random samples from a probability distribution from which direct sampling is difficult. This sequence can be used to approximate the distribution (e.g. to … See more The algorithm is named for Nicholas Metropolis and W.K.
