BLUE of Regression Coefficient Matrices in the Growth Curve Model with Possibly Singular Covariance
Gui Yong-xin · Journal of Xianning Teachers College · 2004
In this paper, we give BLUE of regression coefficient matrix in the GCM with possibly singular Covariance, especially as a by-product of the result in Σ0,meanwhile give conditions for coincidence of the BLUE and LSE.
