Figure 1.

Figure 1

MCRE of Locally Efficient and Simple Augmented GEE Relative to Standard (Unaugmented) GEE. Continuous clustered outcomes. Estimators corresponding to each curve are denoted by ‘Estimator-Outcome Regression’ using the abbreviations: Loc Eff-Locally Efficient, Simp-Simple Augmented, Std-Standard; C-Correct, M1-Model 1, M2-Model 2. All estimators use exchangable working covariance for V(Y|A) and V{E(Y|X,A)}. The order of curves in the legend follows the order curves on the figure, with sets of superimposed curves denoted by ‘()’, ‘[]’, or ‘{}’.
