anyone help me to solve it? Thanks log(wage)=
alpha1*log(SUM(Yi*exp(alpha2*di))
whereas
Yi=GDP, i=1,2,3...n
di=distance , i=1,2,3.....n
I have the variables (GDP dan distance) and I have to estimate the
alpha1 and alph2. However, I could not solve it. it says its a nonlinear
regression but I dont know how to solve it>>
The sum part seems like a bit of a red herring. It looks like a linear
combination inside a nonlinear regression. You probably want to look at
-nl-, which does nonlinear least squares.
