CBPS (0.4)

R Package for Covariate Balancing Propensity Score.


CBPS is an R package that implements the covariate balancing propensity score proposed by Imai and Ratkovic (2013; JRSSB). The propensity score is estimated such that it maximizes the resulting covariate balance as well as the prediction of treatment assignment. The method, therefore, avoids an iteration between model fitting and balance checking. The package also implements the generalization of CBPS to the longitudinal settings so that it can be used in conjunction with marginal structural models (Imai and Ratkovic, 2013a). In the future it will be extended to other settings including non-binary treatments and the generalization of experimental and instrumental variable estimates.
