Bayesian Modeling Using the MCMC Procedure
Chen, Fang; SAS Institute 2009
Abstract
Bayesian methods have become increasingly popular in modern statistical analysis and are being applied to a broad
spectrum of scientific fields and research areas. This paper introduces the new MCMC procedure in SAS/STAT 9.2,
which is designed for general-purpose Bayesian computations. The MCMC procedure enables you to carry out analysis
on a wide range of complex Bayesian statistical models. The procedure uses the Markov chain Monte Carlo (MCMC)
algorithm to draw samples from an arbitrary posterior distribution, which is defined by the prior distributions for the
parameters and the likelihood function for the data that you specify. This paper describes how to use the MCMC
procedure for estimation, inference, and prediction.
