OLSMultipleRegression seems to fail on the Filippelli Data

    XMLWordPrintableJSON

    Details

      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.
