Background: I want to compare two polynomal fits and decide if they are significantly different. One way would be to compare the fit variables. Is this legit or is there any other way in origin to (ANOVA-) compare two fits? Thanks for any advice! cheers b and Origin Ver. and Service Release (Select Help-->About Origin): Operating System: [/quote]   Check here to include your profile signature.
