Ols efficiency
Web28. jun 2008. · However, Kadiyala (1968) and Maeshiro (1976, 1978) have argued that OLS is more efficient than C-O when the independent variable is trended and the autocorrelation coefficient is positive. Webmimics the efficiency of the intercept, except for large sample size; the efficiency of the OLS estimator appears to be nearly as efficient as the GLS estimator forρ ≠ ±.9. The …
