I'm interested in the values of a and b, their uncertainity, and the chi-squared value. Does Origin already have this capability and if so how would I access it. Any help would be greatly appreciated. Thank you very much! [/quote]   Check here to include your profile signature. Check here to subscribe to this topic.
