in reply to Data Regression Utility

Just a suggestion -- you might consider writing your OLS in matrix notation, and then using PDL to sling the matrices, rather than handling all the messy algebra scalar-wise. The matrix approach would also give you multivariate OLS for free, vs. just the single dimensional y=mx+b.

    I was looking for a way to do the work in matrix notation, but was not aware of a method to go about writing it. I will investigate PDL. Thanks,
