Dear friends,
I needed to use y = A0 + A*(1-exp(-x/Tau)) to fit some curves in Origin C. After every fitting, I will get the following parameters besides Kai-square and R-square:

A0, error0 (this is the error for A0)
A1, error1 (this is the error for A1)
Tau, error2 (this is the error for Tau)

My question: is error0-2 meaningless? How did the Origin get the errors --- what is the fitting details?

Thanks a lot!
Tony
