Re:Nonlinear fit to inverse power law data plot

Hello,
I have a set of data that when plotted, produces a curve that is
definitely of a inverse-power-law form;

 y=constant*x^-n       where n may be a non-integer.

I have tried the nonlinear fit function with model function forms,
however, I have not been able to get a non-integer value for n.

Does anyone have any ideas?

Thanks in advance for your help!

Regards,
Debbie Leddon
