Members of statalist:
In my econometric project I intend to estimate a model with
nonlinearities. The model could be:
lnC = A+a*sin(b*x)+B*cos(d*x) +k*lnE+g*lnS,
where A, a, b, B, d, k and g are parameters to be estimated. C and x, E
and S are variables. (the meaning of the sign " * ", means d multiplied
by x).
The interesting thing with this model is the nonlinear trigonometric
part of the model. Does anyone know how to formulate/programme such a
nonlinear function in stata?
