Abstract

The random walk Metropolis (RWM) is one of the most common Markov Chain
Monte Carlo algorithms in practical use today. Its theoretical properties have been extensively
explored for certain classes of target, and a number of results with important practical
implications have been derived. This article draws together a selection of new and existing
key results and concepts and describes their implications. The impact of each new idea on
algorithm efficiency is demonstrated for the practical example of the Markov modulated Poisson
process (MMPP). A reparameterisation of the MMPP which leads to a highly efficient
RWM within Gibbs algorithm in certain circumstances is also developed.
