----------------------------------------
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.
