Hi Statalisters,

I've run into a problem using suest after streg. I have nine models, and
I'm comparing regression coefficients between various pairs. (Each model
is a different failure type, but that's not important right now. All
independent variables are identical among models.)

The problem arises thusly:

stset ...
streg ...
est store A

stset ...
streg ...
est store B

suest A B

I get the following error: "score variable for model A contains missing
values"

The thing is that I don't always get the error message. About 3 of the
nine models can be paired together.

I found this: http://www.stata.com/statalist/archive/2005-12/msg00795.html

Is there any chance this is a similar bug? Or am I missing something?

Many thanks!
