This paper uses a decision theoretic approach for updating a probability measure representing beliefs about an unknown parameter. A cumulative loss function is considered, which is the sum of two terms: one depends on the prior belief and the other one on further information obtained about the parameter. Such information is thus converted to a probability measure and the key to this process is shown to be the Kullback-Leibler divergence. The Bayesian approach can be derived as a natural special case. Some illustrations are presented. © The Institute of Statistical Mathematics, Tokyo 2012.

Abstract

This paper uses a decision theoretic approach for updating a probability measure representing beliefs about an unknown parameter. A cumulative loss function is considered, which is the sum of two terms: one depends on the prior belief and the other one on further information obtained about the parameter. Such information is thus converted to a probability measure and the key to this process is shown to be the Kullback-Leibler divergence. The Bayesian approach can be derived as a natural special case. Some illustrations are presented. © The Institute of Statistical Mathematics, Tokyo 2012.
