| Abstract |
We investigate the problem of estimating the mean vector of a multivariate normal random vector x with general quadratic loss function. Some estimators which are different from BHATTACHARYA's one and have simpler form are shown to have uniformly smaller risk than x. A generalization of BHATTACHARYA's result is also given.
