### Covariate Distribution Balance via Propensity Scores. (arXiv:1810.01370v3 [econ.EM] UPDATED)

This paper proposes new estimators for the propensity score that aim to maximize the covariate distribution balance among different treatment groups. The proposed propensity score estimators, which we call the integrated propensity score (IPS), are data-driven, do not rely on tuning parameters such as bandwidths, admit an asymptotic linear representation, and can be used to…
