WebThe “propensity score” pˆ is an estimate for P(X= 1 Z1,Z2), that is, the conditional probability of ﬁnding the subject in the treatment group given the confounders. Subjects with X = 1 receive weight 1/pˆ; subjects with X= 0 receive weight 1/(1 −ˆp). A “weighted” regression minimizes the weighted sum of squares.
