Hello everybody,

I am writing this topic because I am looking for some help in modeling an example about NLS, WNLS, and FGNLS regression in R. You can see the results of the estimation in the picture below.

This is the link to the code used by the autheurs with Stata http://faculty.econ.ucdavis.edu/faculty/cameron/mmabook/mmaprograms.html

Ans this is The database http://faculty.econ.ucdavis.edu/faculty/cameron/mmabook/mma05data.asc

What I want to do, is to find the same results as they are in the book (see the picture below), but I can only find the results of the OLS estimation.

I desperately need help! It doesn't seems so complicated, but I couldn't find it... Any help would be very appreciated! Thanks
