st: nonlinear sureg

[Camilla Andersson <camilla.andersson@econ.umu.se>]

Dear all,

Is it possible to estimate SUREG when the regressions are nonlinear in the 
parameters?

I want to estimate a system that looks like this:

Y1=exp(alfa1 X1)*( beta1+beta2 X2)
Y2=exp(alfa1 X3)*( beta1+beta2 X4)

How can I do this?

Kind Regards

Camilla Andersson
