Origin Ver. 8.6
Operating System:Mac OS X
Dear All,
I am trying to fit following function
(G/(n*x))*(1-((T/G)*(log(k/(log(r)*x))+(G/T)+0.577216))^n)
with initial parameters x=0.4; k=1E-3; G=100; are not fixed
and T=4.13; n=0.66666; are fixed
to following data
dropbox.com/s/k9ru7xf45t04vsw/Data
However fit is not converging, I tried also different values of parameters but still did not get the fit. Is anyone knows how to solve this issue.

I am fitting on log linear scale (X axis Log, Y axis linear ) |
