WebGLS is referred to as generalized least square (GLS) estimator. Let us deﬁne the corresponding GLS estimator of E(Y) as Yˆ GLS = Xβˆ GLS = X(XTV −1X)gXTV −1Y = P GLSY, (5.2.8) where PGLS = X(XTV −1X)gXTV −1. When X is of full rank, (XTV −1X)−1 exists and the GLS estimator becomes βˆ GLS = (X TV −1X)−1XTV −1Y. (5.2.9) In ... WebThe basic idea behind GLS is to transform the observation matrix [y X] so that the variance in the transformed model is I (or σ2I). Since V is positive definite, V-1 is positive definite too. Therefore, there exists a nonsingular matrix P such that V-1 = P′P. Transforming the model y = Xβ+ εby P yields Py = PXβ+ Pε. Note that EPε= PEε ...

WebGeneralized least squares (GLS) estimates the coefficients of a multiple linear regression model and their covariance matrix in the presence of nonspherical innovations with known covariance matrix. The setup and process for obtaining GLS estimates is the same as in FGLS , but replace Ω ^ with the known innovations covariance matrix Ω . WebLECTURE 11: GENERALIZED LEAST SQUARES (GLS) In this lecture, we will consider the model y = Xβ+ εretaining the assumption Ey = Xβ. However, we no longer have the assumption V(y) = V(ε) = σ2I. Instead we add the assumption V(y) = V where V is positive definite. Sometimes we take V = σ2Ωwith tr Ω= N As we know, = (X′X)-1X′y. What is E ?

Webi you can estimate by GLS (not just feasible GLS), because you divide the variable by the observable x i and you the variance of u i equal to the unknown ˙2, but that is the standard OLS situation.
