Abstract
In this article we consider the partitioned fixed linear model F: Y = X1β1+ X2β2 + ε" and the corresponding mixed model M: Y =X1β1+X2u+ ε, where ε is a random error vector and u is a random effect vector. In 2006, Isotalo, M¨ols, and Puntanen found conditions under which an arbitrary representation of the best linear unbiased estimator (BLUE) of an estimable parametric function of β1in the fixed model F remains BLUE in the mixed model M. In this paper we extend the results concerning further equalities arising from models F and M.
