Use of stabilized inverse propensity scores as weights to directly estimate relative risk and its confidence intervals
OBJECTIVES: Inverse probability of treatment weighting (IPTW) has been used in observational studies to reduce selection bias. To obtain estimates of the main effects, a pseudo data set is created by weighting each subject by IPTW and analyzed with conventional regression models. Currently variance...
