Web3. When we talk about consistent estimation, we mean consistency of estimating the parameters β from a regression like. y = α + β x + u. We don't know the true value of the slope of x in this linear model, i.e. we don't know the true value of β. This is why we estimate it in the first place. WebApr 1, 2013 · The best linear unbiased estimator (BLUE) of parametric functions of the regression coefficients under a general linear model M = { y, X β, σ Σ } can be written as , where G is the solution of a consistent linear matrix equation composed by the given matrices in the model and their generalized inverses.
