Is there any way that this could be made into a fortune -- perhaps by omitting the poster's identity?
"yes there are threads concidering this topic but they are all about the theory not about how to get the value of r^2 for a non-linear model in R." :=) Cheers, Bert Anna: I say this because you have just been told that the "theory" tells you that you CANNOT calculate R^2 for a nonlinear model.
