LOPEZ, L.A. and IEMMA, A.F.. ON THE ESTIMATION AND PREDICTION IN MIXED LINEAR MODELS. Sci. agric. [online]. 1998, vol.55, n.2, pp. 291-295. ISSN 1678-992X. http://dx.doi.org/10.1590/S0103-90161998000200019.
Beginning with the classical Gauss-Markov Linear Model for mixed effects and using the technique of the Lagrange multipliers to obtain an alternative method for the estimation of linear predictors. A structural method is also discussed in order to obtain the variance and covariance matrixes and their inverses.
