Propensity score models

["Peter Flom" <flom@ndri.org>]

I recently attended a talk on Propensity Score Models by Rajeev
Dehejia.
It was very interesting.  It's a method for dealing with sampling bias
in nonexperimental studies.

I was wondering if anyone had programmed this in S Plus?

Thanks

Peter
