Don't know if it's the protocol here, but I thank you very very much. I already have an idea for solving this issue. I'll let you know.

Dear Friends, I have a set of data to fit to a custom equation, y=a+b*exp(k*x), would you advice me on the how to, or tutorial?

Re: [Tutor] fit data to equation
Dear Alan and Oscar
Thank you.
I'll try to be more accurate:

It's a variation , of a physical value ("y") in time ("x") (while
cooling) , you have the data measured (xi, yi), but not from x=0. I need to
extrapolate "y" to "x=0", by that equation.
I know the very basics about statistics, and a beginner in python, I ve
chosen python to work with.
