Web• Note that WIC only requires weakly exogenous regressors. • For cross-section data, the regressors are most likely to be strictly exogenous. But, strictly exogenous regressors are rare in time-series data models. • When regressors are weakly exogenous, GLS may be inconsistent. Even when GLS and FGLS are consistent, the asymptotic WebComparing OLS and FGLS with autocorrelation –For consistency of FGLS more than the strict exogeneity assumption is needed because the transformed regressors include variables from ... •This is useful because FGLS requires strict exogeneity and assumes a very specific form of serial correlation (AR(1) or, generally, AR(q))
