Regression

[Daniel Carrera <dcarrera math toronto edu>]

I have rewritten my program in Python.  I have tested it and debugged it.

However, the results are disappointing:

The procedure only converges to the right values if the initial guess of
the parameters is very close to their actual values (in which case in
converges very quickly).


My plan is to implement an entirely different algorithm and try again.  I
will implement the Levenberg-Marquardt Method.  Hopefully that one will
give more satisfactory results.

I'll report back when I have some results.

Daniel.
