Subject [jira] [Created] (SPARK-6160) ChiSqSelector should keep test statistic info
Date Wed, 04 Mar 2015 19:12:38 GMT
Joseph K. Bradley created SPARK-6160:
----------------------------------------

             Summary: ChiSqSelector should keep test statistic info
                 Key: SPARK-6160
                 URL: https://issues.apache.org/jira/browse/SPARK-6160
             Project: Spark
          Issue Type: Improvement
          Components: MLlib
    Affects Versions: 1.3.0
            Reporter: Joseph K. Bradley
            Priority: Minor


It is useful to have the test statistics explaining selected features, but this is thrown
out when constructing the ChiSqSelectorModel.  It is expensive to recompute.  The ChiSqSelectorModel
should store and expose it.
