Nonlinear model (with country and time fixed effects)

[Mecit Yildirim]

I try to estimate the above nonlinear model by Stata. Unfortunately, I am not comfortable with Stata. Can anyone help me about writing the above function in Stata? How can we write regional dummy, time fixed effect and country fixed effect in nl command in Stata? Is there a way to write the summation in the above equation in Stata? Alternatively, is it easier to estimate the equation for each individual region?

Does the information above is adequate for answer?

You'll increase your chances of a usefulo answer by following the FAQ on asking questions - provide Stata code in code delimiters, readable Stata output, and sample data using dataex.

This looks like non-linear least squares (command nl) with dummies for the fixed effects.
