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
