Optimal Robustness Results for Some Bayesian Procedures and the Relationship to Prior-Data Conflict

Statistics Theory 2015-04-28 v1 Statistics Theory

Abstract

The robustness to the prior of Bayesian inference procedures based on a measure of statistical evidence are considered. These inferences are shown to have optimal properties with respect to robustness. Furthermore, a connection between robustness and prior-data conflict is established. In particular, the inferences are shown to be effectively robust when the choice of prior does not lead to prior-data conflict. When there is prior-data conflict, however, robustness may fail to hold.
