Using Propensity Scores with Quasi-Experimental Designs, Sage Publications

William M. Holmes

The following sites contain programs for doing propensity score matching.  Some programs also do Mahalanobis distance matching, with or without matching by fixed characteristics or use of calipers. For programs other than matching when using propensity scores, see http://www.sage/holmes/ or http://www.faculty.umb.edu/william_holmes/propensity.htm . The entries below list the URL for the program and the author’s name(s).
