Hi!
I am writing my thesis and was not able to curve-fit an expression and am in need of some *desperate* help! I have attached the files containing all data and the mathematica file - please change the path in the .nb file before running it. Basically, I am trying to fit the following equation:

(delta/g[zmax,n]) * g[zmax E/Emax, n];
where
g[z_,n_] := (1 - Exp[-z^(n+1)])/z^n;

I have figured the problem is with the "Exp" part. The program works fine if n=0.35 AND g[z_,n_] is defined as,
g[z_,n_] := Abs[(1 - Exp[-z^(n+1)])/z^n] but gives
rubbish values for the fit parameters.

I am not quite sure where I am going wrong. Any help would be appreciated. Thanks in advance.
