The risk of pretest and shrinkage estimators. (English) Zbl 1241.62095
Summary: We establish the risk function of a class of estimators for the mean parameter matrix of a matrix variate normal distribution. In particular, the established result is useful in evaluating the performance of a class of shrinkage-pretest-type estimators.
