[jira] [Created] (MATH-615) OLSMultipleRegression seems to fail on
the Filippelli Data
OLSMultipleRegression seems to fail on the Filippelli Data
----------------------------------------------------------
Key: MATH-615
URL: https://issues.apache.org/jira/browse/MATH-615
Project: Commons Math
Issue Type: Bug
Affects Versions: 3.0
Environment: Java
Reporter: greg sterijevski
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.

The situation is not as dire as I first thought. The original test I uploaded had a bug which resulted in a singular matrix, correctly. This current test still fails, but the failure occurs with a tolerance of 1.0e-5 for the parameters.

---------------------------------------
Yes, the major issue of singularity was one where I had a bug in the test.

I am tempted to close this as not a problem. What do you think, Greg?
