    Following a wider interpretation proposed by Rao (), weighted-least-squares estimators of XB under the general Gauss-Markov model {Y, Xß, σ 2 V} are considered in this paper as the family of all statistics of the form Xb w = X(X′WX) − X′WY, where W may be any matrix satisfying the condition k (X′WV) ⊂ k (X′WX) ≠ {0}. Several properties of such estimators Cited by: The Gauss-Markov theorem specifies the conditions under which the ordinary least squares (OLS) estimator is also the best linear unbiased (BLU) estimator.

On the theory of Gauss-Markov estimators by Hilmar Drygas Download PDF EPUB FB2

The Gauss‐Markov theorem is the famous result that the least squares estimator is efficient in the class of linear unbiased estimators in the regression model. The efficiency of an estimator. The Gauss-Markov theorem states that, in the class of conditionally unbiased linear estimators, the OLS estimator has this property under certain conditions.

Key Concept The Gauss-Markov Theorem. The so-called Gauss-Markov theorem states that under certain conditions, least-squares estimators are “best linear unbiased estimators” (“BLUE”), “best” meaning having minimum variance in the class of unbiased linear estimators. The Gauss–Markov theorem states that, under very general conditions, which do not require Gaussian assumptions, the ordinary least squares method, in linear regression models, Author: Marc Hallin.
