In the video show below I demonstrate how to perform propensity score stratification.
An alternative method of using strata in propensity score analysis is to perform marginal mean weighting through stratification. It is a more flexible method than traditional propensity score stratification because it can be easily combined with weighted estimation of any parametric model. In the video below I demonstrate marginal mean weighting through stratification.
