Hello,

is there a possibility to define another merit function for the nonlinear fitter? I mean for normally distributed measurements one fits by minimizing the Chi2 (eventuelly weighted).
I have data that obeys the binominal distribution and would like to fit it.

Thus I would need to redefine the merit function that has to be minimized. Can I do this in origin? Does somebody know another program that does it?

Thanks a lot for your help,

Frank
