[math] Improving numerics in OLSMultipleLinearRegression

While clear and elegant from a matrix algebra standpoint, the "nailve" implementation in OLSMultipleLinearRegression has bad numerical qualities. It is well known that solving the normal equations directly does not give good numerics. I just added some tests to actually verify parameter value
