bakaimi	Posted - 03/02/2012 : 04:53:33 AM Origin Ver. and Service Release (Select Help-->About Origin): Operating System:origin 8.0 Hi! I have created my own FDF file with the function : y=a(1-x/c)^2b where I give to a and c standard values, x independent variable and I want to calculate b. The code function and the fdf file is saved but I can't do the fitting! Any ideas on how to fix it?? thanks Ioanna

bakaimi	Posted - 03/02/2012 : 10:04:07 AM Hi Hideo I used the function y=x^A by adjusting my data for this equation and it works! thanks anyway quote: Originally posted by Hideo Fujii Hi bakaimi, Have you put * for multiplication like : y=a(1-x/c)^(2b) 2*b is ambiguous, so I put it in a pair of parentheses, though this might be different from what you intended. --Hideo Fujii Originlab
