Abstract: |
In this paper, the superiority of the Bayes linear unbiased estimators of unknown parameters in a class of linear models is studied. By using the theory of matrix, we obtain the conditions of the Bayes linear unbiased estimators to be superior to the generalized least squares estimator under the balanced loss criterion and the MSEM criterion, respectively. |
