(b) In the following ‘True or False questions, we consider the classical assumptions for OLS, except for the variance-covariance matrix 1 of the disturbance term. If 2 0 0 -- 02 Ω = σ2 ... 0 0 2 0 GLS is more efficient than OLS. (c) If 0 0 ... 0 Ω: : - = a2 0 : 0 ... 0 OLS is BLUE. (d) If Ω = σ2 1 0 0 1 0 1 1 0 0 1 1 0 1 0 0 1 OLS is BLUE.
