WebAug 24, 2024 · A Monte Carlo Markov Chain (MCMC) is a model describing a sequence of possible events where the probability of each event depends only on the state attained in the previous event.MCMC have a wide array of applications, the most common of which is the approximation of probability distributions. Let’s take a look at an example of Monte Carlo … WebA Markov Chain is a mathematical process that undergoes transitions from one state to another. Key properties of a Markov process are that it is random and that each step …
