st: Question about sureg

["Nuno" <liststata@gmail.com>]

Hi everyone,

I would like to run the following system of unrelated equations using
-sureg-, but I don't know if the command is able to do this:

y1=a0+a1*x1+a2*x2+u
y2=b(y1-a0-a1s*x1-a2s*x2)+v

Does anyone have an idea of how to set the -sureg- command in order to
estimate this system of equations?

Best,

Nuno
