Matlab/Octave package BayesBT

This Matlab/Octave package implements EM and Gibbs sampling algorithms for Bayesian inference in Bradley-Terry and Plackett-Luce models (Caron and Doucet, 2012). These models are very popular to deal with data consisting of pairwise or multiple comparisons of a set of items.

Gibbs sampling
Gibbs sampling This week we will look at how to construct a Gibbs sampler for sampling from full conditionals of multivariate distributions, and how to carry out a basic analysis of the output. First read carefully through the following example, trying it out as you go along, then tackle the exercises below.

Gibbs sampling
Gibbs sampling In the Gibbs sampling algorithm, we start by reducing all the factors with the observed variables. After this, we generate a sample for each unobserved variable on the prior using some sampling method, for example, by using a mutilated Bayesian network.

Bayesian Mixture Models and the Gibbs Sampler

 · PDF 檔案‚ SeeFigure 1for Gibbs sampling for Gaussian mixtures. ‚ Note that within an iteration, when we sample one variable its value changes in what we subsequently condition on. E.g., when we sample 1, this changes what 1is for the subsequent samples.
