Title: estimation of nonlinear simultaneous equations system
Dear Stata listers,
I would like to estimate a nonlinear simultaneous equation system using Stata, for example:
Y1(t) = F[X1(t),X2(t); p] +U1(t)
Y2(t) = G[X1(t),X2(t); p] +U2(t),
where Y1 and Y2 are dependent variables, X1 and X2 are explanatory variables, U1 and U2 are possibly correlated error terms, and p is the vector of parameters to be estimated.
All I know about nonlinear estimation from Stata is the "nl" routine for a single equation estimation.
Could anyone help me to implement this estimation using Stata? I will appreciate it much.
