> ChiSqSelector should keep test statistic info

> 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
> these data are thrown out when constructing the ChiSqSelectorModel. The data
> are expensive to recompute, so the ChiSqSelectorModel should store and expose
> them.
