Best answer

The propensity score e(x): the probability of a unit receiving a treatment given covariates

 

Two key properties

  1. The propensity score e(X) balances the distribution of all observed covariates X between the treatment groups
  2. If the treatment is unconfounded given X, then the treatment is unconfounded given e(X)
