Feynman Liang created SPARK-9090:
------------------------------------

             Summary: Fix definition of residual in LinearRegressionSummary
                 Key: SPARK-9090
                 URL: https://issues.apache.org/jira/browse/SPARK-9090
             Project: Spark
          Issue Type: Bug
          Components: ML
            Reporter: Feynman Liang
            Priority: Trivial


Residual is defined as label - prediction (https://en.wikipedia.org/wiki/Least_squares); we need to update {{LinearRegressionSummary}} to be consistent.
