Prior Processes

This chapter is devoted to introducing various prior processes, their formulation, properties, inter-relationships, and their relative strengths and weaknesses. The sequencing of presentation of these priors reflects mostly the order in which they were di

Preface

The foundation of the subject of nonparametric Bayesian inference was laid in two technical reports: a 1969 UCLA report by Thomas S. Ferguson (later published in 1973 as a paper in the Annals of Statistics) entitled “A Bayesian analysis of some nonparametric problems”; and a 1970 report by Kjell Doksum (later published in 1974 as a paper in the Annals of Probability) entitled “Tailfree and neutral random probabilities and their posterior distributions”. In view of simplicity with which the posterior distributions were calculated (by updating the parameters), the Dirichlet process became an instant hit and generated quite an enthusiastic response. During the decades of 1970s and 1980s, hundred
