st: predict residual after treatreg

[Shehzad Ali <sia500@york.ac.uk>]

Hi,

Apologies for re-posting. My previous message went as a reply rather than a 
fresh query.

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'.

I need the residuals for further analysis. Any help would be appreciated.

Cheers,

Shehzad
