I do regression using NumPy; it works fine for me. I guess if it became
really essential to go to C one should build a proper regression module.
My main problem with these public data sources is that they're not
always available. Here in the UK yahoo seems to have made quotes.csv
produce xls files; an insanity of course for us, but sensible for yahoo.
