Ordering of nonnegative definite matrices with application to comparison of linear models
Several necessary and sufficient conditions are given in terms of generalized inverses that two real nonnegative definite matrices \(M_ 1\) and \(M_ 2\) satisfy \(M_ 1\geq M_ 2\). The results are applied to comparison of statistical linear models.
