Thanks, Martin and Nick. I will use - gen - to get my residuals.

Subject: Re: st: RE: predict residual after treatreg
Following Martin's suggestion:
1. It is evident that -predict- after -treatreg- does not support
residual calculation. Thus you are asking for something not provided by
Stata, as Stata is indeed telling you.
2. I can't comment on why not. But it would seem that
predict predicted
gen residual = y - predicted
is what you need for vanilla flavour residuals. If you want some other
flavour, the same tactic is indicated: you should use what is provided
by -predict- as building blocks.

Alternatively type -h treatreg postestimation-

I am trying to predict residuals after running treatreg command. Here is
what I am doing:
treatreg y x1 x2 x3, treat (x1=x2 x3 x4) twostep
predict r, resid
treatreg command works but predict command gives this error 'option resid
not allowed'.
