[jira] [Created] (SYSTEMML-1455) Change the term PLAIN_R2 to R2 in all algorithms

Imran Younus created SYSTEMML-1455:

             Summary: Change the term PLAIN_R2 to R2 in all algorithms
                 Key: SYSTEMML-1455
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1455
             Project: SystemML
          Issue Type: Improvement
          Components: Algorithms
            Reporter: Imran Younus
            Priority: Trivial


In some of the regression algorithms, we return several metrics. One of these is R2. But we call if PLAIN_R2. This is unconventional. We should just call it R2. I've never see the term PLAIN_R2 in any book or paper or software etc. There is R2 and Adjusted R2. I think it would be better to use the conventional terminology as mush as possible.
