Origin Ver. and Service Release (Select Help-->About Origin): 8.5.1 SR2
Operating System: Windows XP

Hello,

When performing nonlinear fitting I would like to weight my responses by the squared inverse of the fitted curve. Does the weighting option "Variance ~ y^2" accomplish this? I want to be sure I am using the estimated curve and not the actual data points. If this function does not how can I do this?

Thanks!

I believe I have answered my own question. The 'Variance ~ yfit^2' option is what I want. Thanks anyway!
