Since there has been a great deal of interest in matching lately, there is a neat article in Statistical Science, v. 25 #1 by Elizabeth A Stuart entitled Matching Methods for Causal Inference: A Review and a Look Forward. The IMS makes everything available on line so you can get it from http://www.imstat.org/publications/eaccess.htm

Thank you for your insights about bootstrapping. I wiill try adjusting your
code to my situation to reproduce the T-stat and compute the p-value.
I am, however, still confused about two very simple things:
1. What is the T-stat for the ATT actually telling us? Is this the T-stat for
the comparison of treatment vs control matched groups?
2. How do we determine if there is a treatment effect?
