Linear Restrictions on Parameters in linear regression model with non-spherical disturbalances
Fikri Akdeniz · Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics · 1980
in this paper we are concerned with the estimation of parameters snbject to linear constraints. No rank conditions are imposed on R,X and V. The results are applied to obtain the generalized inverse of X'V+X which ^ ields a solution of the normal equations snbject to nonestimable constraints on the parameters.
