Some Admissible Empirical Bayes Procedures

This paper considers some empirical Bayes procedures which have been discussed by H. Robbins, E. Samuel, and M. V. Johns. These procedures are shown to be inadmissible relative to a class of priors and by using some of the results of Rolph [6] admissible procedures are found for two examples. For an introduction to the empirical Bayes approach see Robbins [5].
