A Zero-Math Introduction to Markov Chain Monte Carlo Methods

|

So, what are Markov chain Monte Carlo (MCMC) methods? The short answer is: MCMC methods are used to approximate the posterior distribution of a parameter of interest by random sampling in a probabilistic space. In this article, I will explain that short answer, without any math. First, some terminology. A parameter of interest is just…
