Abstract
Asymptotic equivalence of Aitken and feasible Aitken estimators in lin ear models with nonscalar identity error covariance matrices is usuall y established in a tedious case-by-case manner. Some general sufficien t conditions for this equivalence exist, but there are problems with t he extant conditions. These problems are discussed, and new widely app licable sufficient conditions are presented and applied to a variety o f error structures.
