A Unified and Broadened Class of Admissible Minimax Estimators of a Multivariate Normal Mean


  • Maruyama, Yuzo


The problem of estimating the mean of a multivariate normal distribution is considered. A class of admissible minimax estimators is constructed. This class includes two well-known classes of estimators, Strawderman's and Alam's. Further, this class is much broader than theirs.
