-------------------------------------------

Ahh, you're right, sorry, I see that now that I'm looking at master.  I'll link 
the follow-up JIRA to the original JIRA.

And I agree my assertion about p-value wasn't correct.  Will fix.  Thanks!

> There are several cleanups I'd like to make as a follow-up to the PRs from 
> [SPARK-17017]:
> * Rename selectorType values to match corresponding Params
> * Add Since tags where missing
> * a few minor cleanups
> One major item: FPR is not implemented correctly.  Testing against only the 
> p-value and not the test statistic does not really tell you anything.  We 
> should follow sklearn, which allows a p-value threshold for any selection 
> method: 
> [http://scikit-learn.org/stable/modules/generated/sklearn.feature_selection.SelectFpr.html]
> * In this PR, I'm just going to remove FPR completely.  We can add it back in 
> a follow-up PR.
