Finite-sample distributions of the OLS estimator and t-statistics are complicated, unless
A) the regressors are all normally distributed.
B) the regression errors are homoskedastic and normally distributed, conditional on X1,... Xn.
C) the Gauss-Markov Theorem applies.
D) the regressor is also endogenous.
Question 2
In practice, the most difficult aspect of feasible WLS estimation is
A) knowing the functional form of the conditional variance.
B) applying the WLS rather than the OLS formula.
C) finding an econometric package that actually calculates WLS.
D) applying WLS when you have a log-log functional form.
