[non linear estimation (nls)]

Some econometric models cannot be made linear in parameters. The solution is to estimates the parameter by nonlinear techniques. Almost any function that can be written in closed form can be incorporated in a nonlinear regression model.

Unfortunately nonlinear models could not be estimated by analytical. There are only numerical methods, which does not guarantee to find an optimum. Moreover, nonlinear estimation costs more computing time.

 


[notes]

This Add-In uses the Solver Add-In to solve the model iterative. I think the Solver Add-In is a powerful tool to optimise a nonlinear system. Make sure that the Solver Add-in is installed with Excel.

The nonlinear estimation (nls) Add-In was written by Kurt Annen. This program is freeware. But I would highly appreciate if you could give me credit for my work by providing me with information about possible open positions as an economist. My focus as an economist is on econometrics and dynamic macroeconomics. If you like the program, please send me an email.
