Subject: st: Joint Wald test after NLSUR
Dear Statalisters,
After the following NLSUR estimation:
nlsur (y1 = {a1}*x1 + {a2}*( {c} + x2 ) ) (y2 = {b1}*x1 + {b2}*( {c} + x2
) )
how do I test the joint hypothesis that {a2} and {b2} are zero using the
"test" command? I cannot find the right syntax to refer to these two
parameters...
Thank you,
Regio
