Probability Matching Priors: Higher Order Asymptotics Probability matching priors ensuring frequentist validity of posterior credible sets up to the desired order of asymptotics are of substantial current interest. They can form the basis of an objective Bayesian analysis. In addition they provide a route for obtaining accurate frequentist confidence sets which are meaningful also to a Bayesian. This monograph presents for the first time in book form an up to date and comprehensive account of probability matching priors addressing the problems of both estimation and prediction. Apart from being useful to researchers it can be the core of a one semester graduate course in Bayesian asymptotics. Gauri Sankar Datta is a professor of statistics at the University of Georgia.
