Bayesian Analysis of Contingency Tables [PDF]
Communications in Statistics - Theory and Methods, 2005 The display of the data by means of contingency tables is used in different approaches to statistical inference, for example, to broach the test of homogeneity of independent multinomial distributions. We develop a Bayesian procedure to test simple null hypotheses versus bilateral alternatives in contingency tables.
