Dear Stata List Members,

Paul Rosenbaum, in his book Observational Studies, presents formulas for
performing "sensitivity analysis" in observational studies--where the
treatment groups are not assigned randomly.  Sensitivity analysis is used to
estimate the likelihood that hidden bias might account for a statistically
significant association between the treatment and outcome.

I have been unable to find a user-written Stata ado file for performing this
type of sensitivity analysis. Does anyone on the list know if such exists?

Thanks.

Dan Chandler
