Abstract

Liski et al. (1992, Linear Algebra Appl. 176, 121-130) give upper bounds of a criterion and make efficiency comparisons between the ordinary least-squares estimator and the best linear unbiased estimator for a singular linear model. Based on several matrix and trace versions of the Kantorovich inequality, we make further studies to introduce new efficiency criteria, to obtain their upper bounds and to make efficiency comparisons between the two estimators for the same singular linear model in the general case.
