by "model" are you referring to the "LinearRegressionResults"
class I had mentioned?  I'm also no statistical guru.  I can get
around where i need to, but i'm not sure what the "score" method
and "residuals" method is.  I'm guessing you might be referring to
some of the linear regression statistics.  A little clearer explantion
would help.  I could submit what i have, and whomever can do the commit
might want to take these things into account, and possibly refactor
things a bit.  I'm mainly concerened (for my project) with the coefficient
matrix and predictions, but decided to go the extra step of computing
all the statistics that go along with it (figuring the community would
have use for them).

Phil, 100% agree with you. I would be happy to have the problem 
solved in a similar way as in R. Using lm in R is very comfortable.
