Web12 The short answer is: An MCMC is a MC, but not all MCs are MCMC. The slightly longer answer: MC methods are a class of methods, of which MCMC is one possibility. Even … In statistics, Markov chain Monte Carlo (MCMC) methods comprise a class of algorithms for sampling from a probability distribution. By constructing a Markov chain that has the desired distribution as its equilibrium distribution, one can obtain a sample of the desired distribution by recording states from the chain. The more steps that are included, the more closely the distribution of the sample matches the actual desired distribution. Various algorithms exist for co…
