Propensity scores (March 10, 2006). Category: Covariate adjustment

When I have time, I want to describe the use of propensity scores and show some examples. Propensity scores offer a simple and effective way to correct for covariate imbalance in an observational study. An excellent reference on this technique can be found on the web at:
