You're still working on PSPP?
Here are some things I would find interesting (if they are not already
present):
Generic Levenberg Marquardt fitting of families of functions to trend
data (specifically, polynomial degree N, exponential(N), log(N),
N*log(N), 2^N, N!, N^N) and linear combinations thereof.
Here, 'polynomial degree N' might sound like a polynomial of degree
comensurate with the size of the data.
Of course that is not what I meant. Only rarely would I want a
polynomial of degree higher than 5.

Most of the time, it would be of degree 1 (linear) for linear
regression.
