"WebDec 16, 2024 · This method is called Markov chain Monte Carlo. The idea of this method is to do a random walk in the variable space, but try to visit more probable areas more frequently, so that in the resulting sample the histogram follows the probability distribution. Some of the unlikely values in this case have to be rejected. " - Railway markov chain monte carlo and thesis

Web2. In Chapter 3 we will introduce two widely used Markov chain Monte Carlo algorithms, namely the Metropolis and the Glauber algorithms. We then present the mathematical framework for coupling techniques. In Chapters 6 and 7 we present a detailed analysis of the convergence rates Markov chains on the space of proper graph colorings. Our exposition WebThis thesis addresses the application of Bayesian methods to problems in phylogenetics. Specifically, we focus on using genetic data to estimate phylogenetic trees representing the evolutionary history of genes and species. Knowledge of this common ancestry has implications for the identification of functions and properties of genes, the effect ...

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 c… WebIf k= 1 for state i, then we say state iis aperiodic. The Markov chain is aperiodic if all states are aperiodic. It can be shown that an irreducible Markov chain is aperiodic if just one state is aperiodic. A simple example of a periodic Markov chain can be seen in Figure 2. 3 Stationary Distribution and Long Time Behavior 3
