Algebraic Properties of the OLS Estimator. Several algebraic properties of the OLS estimator were shown for the simple linear case. As one would expect, these properties hold for the multiple linear case. The properties are simply expanded to include more than one independent variable. ...

The indirect least squares estimator is introduced in section 3. In section 4 presents the indirect feasible generalized least squares estimator, and briefly discusses maximum likelihood methods. Section 5 develops two rationales for the 2SLS procedure, and the k-class family of estimators …

Least squares method: Estimate 0, 1 using the values that minimize the sum of the n squared deviations. Goal: Minimize • Calculus shows that the estimators (call them b0 and b1) that minimize this criterion are: Then is called the least-squares estimated regression line. • Why are the “least-squares estimators” b0 and b1 “good”?

Algebraic Properties of the OLS Estimator. Several algebraic properties of the OLS estimator are shown here. The importance of these properties is they are used in deriving goodness-of-fit measures and statistical properties of the OLS estimator. Algebraic Property 1. Using the FOC w.r.t. it can be shown the sum of the residuals is equal to ...

Some properties of the least squares estimates are: (i) Unbiased estimators: The means of the sampling distribution of and are and respectively. (ii) Consistent estimators: As the sample size increases, the probability that and will come close and respectively converges to 1. (iii) Minimum variance estimators: The least squares estimators are ...

Properties of least square estimators when the disturbances are auto-correlated. The Durbin-Watson test for auto-correlation. Generalized least squares. Introduction. In the last section we investigated consequences for the least square estimator that the disturbances had varying variances, but otherwise satisfied the classical standard conditions.
