Statistical Issues in the Analysis of Contingency Tables

Adrian Dobra


University of Washington - Department of Statistics

I discuss key questions relating to the analysis of categorical data: the validity of asymptotic approximations to the null distribution of test statistics, exact testing methods, sparsity, structural zeros, incompleteness as well as log-linear model selection. Relevant topics I plan to cover include: computation of sharp integer bounds for cell entries, simulation from probability distributions on spaces of tables, Markov bases and Bayesian inference with conjugate priors. I will give several examples and talk about open problems.
