The Stein phenomenon is a path-breaking discovery in mathematical statistics in the last century. A large number of researchers followed Stein’s footsteps and developed a wide variety of minimax shrinkage point estimators of a multivariate normal mean vector, each dominating the sample mean. More recently, the problem resurfaced, but this time with minimax shrinkage predictive density estimation, illustrating once again the Stein phenomenon In this review paper, we discuss parallel developments for normal and Poisson distributions under the Kullback-Leibler and more general divergence losses.
