Hello everyone,

I would like to ask whether Stata has the function like SAS syslin command,

Here is what I trying to do. my model: y= x1+x2+x1*x2, and I would like to test whether x1+x1*x2 >0.

In Sas I could run as below:

Proc syslin data =one;
Model y = x1 x2 x1*x2;
test x1 + x1*x2 ne 0;
run;

Is there anyway we can do in Stata?

Thanks in advance
