The propensity score (PS) is the conditional probability of assignment to a particular treatment given a vector of observed covariates (Rosenbaum and Rubin 1983). Hirano and Imbens (2004) extended the idea to studies with continuous treatment (or exposure) and labeled it as the generalized propensity score (GPS), which is a …
