Dear STATALISTs,

I am intereset to find a h-ate in a RDD model. In particular, I would like to know if and how to edit the usual command

Code:
rdrobust Y X
Y output, X running variable

if I need to find only the effect of treated in a specific area (for example treated in West). I generated the interaction variable T_W= treat*west, where both treat and west are dummies but I need your help to proceed.

Thanks
