00925njm 22002777a 4500 dc Gómez Villegas, Miguel Ángel author González Pérez, Beatriz author 2005-08-08 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. Given independent samples of two binomial distributions and taking a mixed prior distribution, we calculate the posterior probability that the proportion of successes in the first population is the same as in the second. This posterior probability is compared with the p-value of the classical method, obtaining a reconciliation between both results, classical and Bayesian. The obtained results are generalized for r × s tables. Gómez Villegas, M. A. & González Pérez, B. «Bayesian Analysis of Contingency Tables».
