[jira] [Created] (SPARK-16307) Improve testing for DecisionTree variances

Manoj Kumar created SPARK-16307:
-----------------------------------

             Summary: Improve testing for DecisionTree variances
                 Key: SPARK-16307
                 URL: https://issues.apache.org/jira/browse/SPARK-16307
             Project: Spark
          Issue Type: Test
            Reporter: Manoj Kumar
            Priority: Minor


The current test assumes that Impurity.calculate() returns the variance correctly. A better approach would be to test if the variance returned equals the variance that we can manually verify on a toy data and tree.
