Fig. 1. — Simulation results when only the outcome regression is consistently estimated, with the following performance measures plotted against the sample size : (a) bias; (b) bias; (c) coverage of 95% confidence intervals; (d) accuracy of the standard error estimator. Squares represent estimators that do not account for inconsistent nuisance parameter estimation, circles represent estimators using the bivariate correction of van der Laan (2014), and triangles represent estimators using the proposed univariate corrections.
