st: unable to generate scores for the models in -suest-

[James Bernard <jamesstatalist@gmail.com>]

Hi all,

I am using -suest- to test the difference between coefficients across
two different models.

I am using xtpoisson and running two models named "big" and "small"

so after running one model, i type:
. estimates store big

then the other model

. estimates store big

then I want to compare the coefficient "wage" that exists in both models

.suest big small

I get the following error:

 unable to generate scores for model big
suest requires that predict allow the score option
r(322);

any idea how to get around this?

Thanks
