In this paper, the problem of nonnegative quadratic estimation of the mean squared errors of minimax estimators of/3 in the linear regression model E(y) = X/3, Var(y) = cr2I is discussed. An explicit formula for the admissible nonnegative minimum biased estimator is given. Some applications to one-w
