To illustrate the estimation procedure of the TVP-VAR model, this paper begins by reviewing an estimation algorithm for a TVP regression model with stochastic vola-tility, which is a univariate case of the TVP-VAR model. Then the paper extends the
Chapter 6: Gibbs Sampling - GitHub Pages
jwmi.github.ioimportance sampling. Markov chain Monte Carlo (MCMC) is a sampling technique that works remarkably well in many situations like this. Roughly speaking, my intuition for why MCMC often works well in practice is that (a)the region of high probability tends to be \connected", that is, you can get from one

people.eecs.berkeley.eduattempting to cope with such cases is the Markov chain Monte Carlo (MCMC) framework, and indeed there is a significant literature on the application of MCMC methods to graphical models [e.g., 28, 93, 202]. Our focus in this survey is rather different: we present an alternative computational methodology for statistical inference that is based on
