Title: Some Results on Nonparametric Bayesian Robustness
Author(s): Fabrizio Ruggeri*+
Affiliation(s): CNR-IMATI
Address: Via Ampere 56, Milano, , I-20131, Italy
Keywords: Dirichlet process ; classes of priors ; concentration function
Abstract:

A nonparametric approach to Bayesian robustness is presented. Whereas many studies in Bayesian robustness have dealt with a parametric sampling distribution, considering classes of prior distributions on the parameters, here we assume that the sampling distribution comes from a Dirichlet process with a parameter in a class of measures. Different quantities of interest are analysed.
