I am not sure but may be you should try something like 

roccomp _est_mod1 _est_mod2, graph summary by(dis)

Hi,
I'm trying to use roccomp commande to compare AUC for two logistic
models. but stata won't store my estimates.

here are the commande lines.

* all counts with binary
             logistic dis ref
             est store mod1

             logistic dis stud
             est store mod2
             roccomp dis mod1 mod2, graph summary

and this is the message i have:

variable mod1 not found
r(111);

does anyone know the reason for this?
Best
Edouard
