Good morning everybody

I have a problem with NonLinearRegress. I do not understand the meaning of the values reported in ANOVATable.
I want the squared sum of the residuals (which is the way to judge a fit).
If I perform a non linear regression, and I want to compare the goodness of the two different fits, what is the value of the squared sum of residuals? Is it the value reported in the line "Error"? And what is the meaning of "Uncorrected Total" and "Corrected Total?" What is the parameter I should you use to judge how good my fit is with respect another one?

Coulde someone explain that, please?
Thanks a lot.
Raffaello
