only a consistent one is required t

only a consistent one is required to achieve full efficiency for the FGLS estimator.β ̃is the OLS of the transformed equation, but it is a generalized least square (GLS) estimator of the original regression model which take the OLS as a subcases when Σ = I.Let Σˆ be a consistent estimator of Σ. Then the feasible generalized least squares estimator (FGLS) of β is

只需要相一致的一個以實現FGLS估計全效率。
β是經變換的方程的OLS，但它是一個廣義最小二乘（GLS）內搭OLS作為子情況時Σ= I.原始回歸模型的估計器
設Σ是Σ的一個一致的估計量。然後β的可行廣義最小二乘估計器（FGLS）是

對於FGLS估計器，只有一個一致的才需要達到完全的效率。
β̃是轉換方程的OLS，但它是原始回歸模型的廣義最小二乘估計，當∑=I時，OLS作為子類。
設∑ˆ為∑的一致估計。那麼β的可行廣義最小二乘估計（FGLS）是
