First off, you should note that both -mhbounds- and -rbounds- are
user-written programs. Both can be used directly after psmatch2 or after
running the necessary matching strategies.

As the help file for -mhbounds- states " mhbounds calculates Rosenbaum
bounds for average treatment effects on the treated in the presence of
unobserved heterogeneity (hidden bias) between
treatment and control cases, where both treatment and response variables are
binary". In short, this is the program that does what you are looking for.

-rbounds- is generally used for continuous outcomes, as you can see from the
example in the help file.

For a more comprehensive discussion on sensitivity analyses, I suggest you
read the book by Rosenbaum: Rosenbaum, P.R. (2002) Observational Studies.
2nd edition. New York: Springer. In the relevant sections of this book,
you'll learn what, why and how sensitivity analysis is conducted.

Dear listserve,

I want to check the selection bias after matching. My outcome and
treatment variables both are binary var. For dummy varaibles, what
would be the correct test -rounds or mhbounds, and waht exactly is the
difference between the two?
