Description

Running the Filipelli data results in an exception being thrown by OLSMutlipleRegression. The exception states that the matrix is singular.
http://www.itl.nist.gov/div898/strd/lls/data/Filip.shtml

I have added the data to the OLSMutlipleRegressionTest file.

Unless I screwed something up in the passing of the data, it looks like the QR decomposition is failing.
