WebFeb 1, 2024 · The main strength of propensity score analysis is its ability to reduce a multidimensional problem into an unidimensional one. Once propensity scores have been calculated for each observation, we can ensure that we are properly comparing two possibly different populations, the treatment and control groups. WebThe AIPW method, as our primarily proposed approach, models both the relationships between the treatment and covariates and between the outcome and covariates using a treatment model and an outcome model, respectively. We apply the same set of inverse weights as in the IPW method and modify the existing AIPW estimator according to Li et al.:
