HIERARCHICAL BAYESIAN ANALYSIS OF BINARY MATCHED PAIRS DATA

The paper introduces a hierarchical Bayesian analysis of binary matched pairs data with noninformative prior distributions. Certain properties of the poste- rior distributions, including their propriety, are established. The Bayesian methods are implemented via Markov chain Monte Carlo integration techniques, and nu- merical illustrations are provided. For the logit link, the conditional and marginal maximum likelihood estimators of a treatment effect depend only on the off-main- diagonal elements of a 2 × 2 contingency table, and the same is true of McNemar's test. By contrast, the hierarchical Bayes estimators and subsequent analyses de- pend also on the main-diagonal elements in a natural way.
