Table 3. Monte Carlo Relative Efficiency of Locally Efficient Augmented GEE to Suboptimal Augmented GEE.

Binary clustered outcomes. Working Marginal Covariance (WMCov): Exch-Exchangeable. Outcome Regression (OR): Correct (C), Model 1 (M1), Model 2 (M2), Model 1 OLS (M1 OLS). First entry θ = 1, second entry θ = 0.8. All estimators use exchangable working covariance for V(Y|A) and V{E(Y|X,A)}.
