SOLVED: 1. Consider simple linear regression model (y on z) without an intercepty = x w.points) Derive -the OLS estimator of 3 points) Show that a is unbiased. 3 points) Is TSS ESS RSS? Show it explicitly: 3 points) Obtain Var(a) (2 points If the true model is y = @0 Q13 W and you forgot to include the intercept Is in part (a) unbiased /consistent? Explain in detail. (6 points) If the true model is y = Az 4221 v where 21 is exogenous but is endogenous, derive the IV estimato

The statsmodels ols() method is used on a cars dataset to fit a multiple regression model using Quality as the response variable. Speed and Angle are used as predictor variables. The general form of this model is:Fo   Bi Speed - Bx-AngleIf the level of significance, alpha is 0.10, based on the output shown; is Angle statistically significant in the multiple regression model shown above?

In a two regressor regression model, if you exclude one of the relevant variables thenO b. OLS is no longer unbiased, but still consistent.O d. the OLS estimator no longer exists. O e. All of the above. O f. None of the above.
