Empirical standard errors of the estimated mean scores for an immortal cohort (without single imputation). The figure displays the empirical standard errors of the estimated mean scores (based on 1000 bootstrap samples) for arm A (upper panel) and arm B (lower panel) when considering an immortal cohort. Single imputation has not been applied. The blue dotted-line curve corresponds to the IPW method, the green dash-dotted-line curve corresponds to the LI method, and the red dashed-line curve corresponds to the MP method.
