A Practical Guide to Getting Started with Propensity Scores
support.sas.com"Analysis of Observational Health Care Data Using SAS®", which is published by the SAS Institute, is used to analyze how a health care treatment impacted an associated health care outcome. It details how propensity scores are created and how propensity score matching is used to balance covariates between treated and untreated observations.

Methods for Constructing and Assessing Propensity Scores
www.hcp.med.harvard.edupropensity score’s distribution can be obtained by splitting the sample by quintiles of the propensity score. Astarting test of balance is to ensure that the mean propensity score is equivalent in the treatment and comparison groups within each of the five quintiles (Imbens 2004). If it is not equivalent, one or
