http://sekhon.berkeley.edu/causalinf/fa2014/Slides/Slides_IPSW/slides_IPSW.pdf WitrynaThere are many types of estimators proposed in the literature on treatment effects (see Imbens ). Many exploit the conditional probability of treatment (P (D = 1 X)), also known as propensity scores. These types of ATT estimators can be semiparametric or nonparametric and use propensity scores in a matching procedure.
Witryna4 cze 2024 · The generalized propensity score is a balancing score (Hirano and Imbens 2004; Imai and van Dyk 2004) when the model specification is appropriate. In other words, when observations are grouped into subsets with similar propensity scores, covariates within a subset should be similar among different treatment levels … WitrynaImbens and Rubin (2015) proposed a procedure for estimating the propensity score, with an algorithm for selecting the covariates function further outlined by Imbens …
