I have taken the following values of an experiment: Time / conversion 10 / 19% 20 / 13% 30 / 14,1% 60 / 14,8% 90 / 15,6% 120 / 16,5% Now I want to fit these values except the first value with this model-function: y = A*(1-exp(-B*x)) What shall I do? I've already typed in this new function, but origin does not calculate any parameters. Thanks for your help [/quote]   Check here to include your profile signature.
