You can use the Numpy/Scipy libraries for that. I think they have 
examples for curve fitting on their website. But unfortunately the 
website is down (or my Internet is broken).

There are also special mailing lists for Numpy/Scipy/Matplotlib users, 
to which you should subscribe. This one would be good for your 
question:

If I understand you right, you have a formula with some parameters. 
Now you are searching for parameter values so that the formula really 
goes through the data points. This is a task for optimization 
functions.

Kind regards,
Eike.
