Hello every one

I am in trouble with a fit because I am working with a recursive function and I am not able to write a code to correctly fit my data. Morover, I have to fit several data set at the same time.

The fitting function is:

, where

. In this expression,

. In essence, the functions τ and

are interconnected and I have no idea in which way write these two in my fitting code.

The perameters I want to know are:

while the quantities I know are

Do you have any idea on the way to write this code?
