WebWe review the class of inverse probability weighting (IPW) approaches for the analysis of missing data under various missing data patterns and mechanisms. The IPW methods rely on the intuitive idea of creating a pseudo-population of weighted copies of the complete cases to remove selection bias introduced by the missing data. However, different ... Webprobability-weighted method to account for dropouts under the MAR assumption (Robins and Rotnitzky1995;Preisser, Lohman, and Rathouz2002). The following sections introduce the weighted GEE method and provide a clinical trials example to illustrate how the use of PROC GEE to analyze longitudinal data with dropouts.
