Hi Sasidhar-
This depends on the kind of function it is you want to use. I would recommend going to the Fitting Function Organizer in the Tools menu and from there you'll see all of our built-in functions listed with some descriptions and illustrations of the curves and how they are affected by parameter values.
A quick search shows that wehave two power-law related fitting functions built into the software, including-
the Pareto cumululative distribution function in the Power folder, and Herschel Bulkey model in the Rheology functions folder.
If neither of these or any of the other functions included with our software suit your needs, you can define your own function using the Fitting Function Builder which is also in the Tools folder. For an example of how you would convert a conventional function to the format needed for a fitting function, I would recommend reading this short post and the documentation it links to

And if you have any other questions feel free to write us back!
