Dear All,
 
I was trying to test the sensitivity of treatment effect due to selection on unobserved variables (hidden bias). I have a continuous response (outcome) variable. I checked the 'rbounds' command. However, it implements sensitivity tests for matched (1x1) pairs only. In my case the treated and control group are not matched one to one (see below). In other words the matrix is not (1x1).  Is there other command that I can use in such circumstances. 
 
Thanks,
Menale
