Subject [jira] [Updated] (MATH-615) OLSMultipleRegression seems to fail on the Filippelli Data
Date Wed, 20 Jul 2011 02:46:57 GMT


greg sterijevski updated MATH-615:

    Attachment: filippelli2

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.

> Running the Filipelli data results in an exception being thrown by OLSMutlipleRegression.
The exception states that the matrix is singular. 
> 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.
