Neal Published DOI: In recent years, a great variety of such applications have been described in the literature. Applied statisticians who are new to these methods may have several questions and concerns, however: How much effort and expertise are needed to design and use a Markov chain sampler? How much confidence can one have in the answers that MCMC produces?

Statistical Practice Markov Chain Monte Carlo in Practice: A Roundtable Discussion
Why do I want to do that? Because in the current state of things, we are in possession of such powerful libraries and tools that can do a lot of the work for us. Most experienced authors are well aware of the complexities of implementing such tools. As such, they make use of them to provide short, accessible and to-the-point reads to users from diverse backgrounds. In many of the articles that I read, I failed to understand how this or that algorithm is implemented in practise. What are their limitations? Why were they invented?
Markov Chain Monte—Carlo MCMC is an increasingly popular method for obtaining information about distributions, especially for estimating posterior distributions in Bayesian inference. This article provides a very basic introduction to MCMC sampling. It describes what MCMC is, and what it can be used for, with simple illustrative examples. Highlighted are some of the benefits and limitations of MCMC sampling, as well as different approaches to circumventing the limitations most likely to trouble cognitive scientists. But, what exactly is MCMC?
