Hello,
 
I have to estimate a system of nonlinear equations. I use NLSUR and it works
well.
Now, I want to test linear hypotheses for the parameter am+ac+al=1.
I know using regress it is possible to test. But it is dont work in NLSUR.
Thank you for the helping.
Best regards
Sascha

 

* nlsur - Estimation of nonlinear systems of equations

nlsur
(y={a0}+{am}*m+{ac}*c+{al}*l+{at}*year+0.5*[{amm}*m*m+{acc}*c*c+{all}*l*l+{a
tt}*year*year]+{amc}*m*c+{aml}*m*l+{amt}*m*year+{acl}*c*l+{act}*c*year+{alt}
*l*year) (pfexp =
prexp*[yexp/mexp]*[{am}+{amm}*m+{amc}*c+{aml}*l+{amt}*year]/[1+[{TetaT}
/0.55]]), nls

test am+ac+al=1

 

*  regress - Estimation of regress equations

regress y m c l

test m+c+l=1
