Hi,
I have a problem with nonlinear regression in Mathematica. I want to fit my data (below) to this following equation:
y = Exp[(1-Exp[a*(1-Exp[-b*x])])*(Exp[-b*x])/(1-Exp[-b*x])]
and I would like to find a and b values and also determined r-squared value.
I try to use NonlinearRegression/NonlinearFit code, but its not working, I hope someone could help me
Thanks a lot
