Hello,
Is it possible to fit data using a user defined function in the form of: f(x,y)= a+bx+cy+d*x^2+e*y^2+...
I couldnīt find any way of doing this with the advanced fitting tool nor the fitting wizard!
Thank you very much! Ioana

It is possible to fit such an equation with the NLSF tool in Origin - this is an issue of fitting with multiple independent variables. The only shortcoming is that a surface plot of the data and the fit surface is not automatically created, but the fit parameters will be correct.
