Re: fitting ( cftool )

actually it does say something :
"Fit computation did not converge: Fitting stopped because the number of iterations or function evaluations exceeded the specified maximum."
and :
"Warning: A negative Rsquare is possible if the model does not contain a constant term and the fit is poor (worse than just fitting the mean). Try changing the model or using a different StartPoint."
which says nothig to me.
