In each case we obtain the best linear unbiased estimators of , prove its convergence to ˆ and obtain asymptotic relations. This study is also carried out when the design matrix is not of full rank and when the covariance matrix is nonnegative.journal articlemetadata only access519.22Estadística matemática (Matemáticas)1209 Estadística
