This paper extends the results of Berger [3] by Efron and Morris [5] approach and specifies a class of minimax estimators for β in a linear regression model y=Xβ+u with loss (_??_-β)'Q(_??_-β)/σ2 where Q is arbitrarily fixed. A sufficient condition for a minimax estimator in the class to be minimax under a different quadratic loss is also given.
