Abstract
Gunst and Mason (1976) and Trenkler (1980) have compared several regression estimators with respect to the generalized mean squared error criterion. The purpose of this paper is to deal with the comparisons among the some other biased estimators constructed as alternatives to the least squares estimator when multicollinearity is present.
