NLSF reports the reduced chi^2 value, not chi^2. How can I manage to find the common chi^2 value? For example, Origin give me the reduced khi^2= 1.17, while in the article I revised it pointed out 19,5 (20 degrees of freedom).
Thanks.

Posted - 07/15/2006 : 11:48:43 AM These read-only NLSF properties are available...
nlsf.chisqr = reduced chi^2 nlsf.dof = degrees of freedom nlsf.ssr = sum of squares ("common" chi^2)
They are related through the expression nlsf.chisqr = nlsf.ssr/nlsf.dof.
