Description:

Documentation

Fixes issue

Reconciles comments made on the quantile methods pull request, which is PR five-eighty-eight #588. I'm avoiding referencing that PR with an Arabic numeral because I don't want the approval of this pull request to interfere with that one. However, merging this pull request should resolve the comments I made on five-eighty-eight.
