Since the publication of the first edition of "Empirical Bayes methods" in 1970, there have been many contributions to the theory known as the empirical Bayes approach. This book collects and presents practical examples of the application of empirical Bayes ideas and techniques. The main changes that have been made are: inclusion of more details of published accounts of applications, more emphasis on linear EB methods, an account of some competitors of EB, a chapter on interval estimation, more material on multiparameter problems
