Necessary and Sufficient Conditions for High-Dimensional Posterior Consistency under $g$-Priors

Statistics Theory 2015-09-04 v1 Statistics Theory

Abstract

We examine necessary and sufficient conditions for posterior consistency under gg-priors, including extensions to hierarchical and empirical Bayesian models. The key features of this article are that we allow the number of regressors to grow at the same rate as the sample size and define posterior consistency under the sup vector norm instead of the more conventional Euclidean norm. We consider in particular the empirical Bayesian model of George and Foster (2000), the hyper-gg-prior of Liang et al. (2008), and the prior considered by Zellner and Siow (1980).
