[jira] [Created] (MATH-694) Remove XxMoment statistics from the
public API
Remove XxMoment statistics from the public API
----------------------------------------------
Key: MATH-694
URL: https://issues.apache.org/jira/browse/MATH-694
Project: Commons Math
Issue Type: Improvement
Affects Versions: 2.2, 2.1, 2.0, 1.2, 1.1, 1.0
Reporter: Phil Steitz
Fix For: 3.0
The Second, Third and FourthMoment statistics in o.a.c.m.stat.descriptive.moment are non-standard and are really just there to make updating more efficient in other statistics that embed them and the aggregates. The naming is misleading and I am not sure there is much independent value to these statistics, so I propose that we change them to have package scope in 3.0. I am happy to close this as WONT_FIX if anyone has objections.

[jira] [Commented] (MATH-694) Remove XxMoment statistics from the
public API

Phil Steitz commented on MATH-694:
----------------------------------
I did not reduce visibility of SecondMoment, because that statistic is used in several places outside its package. If anyone feels strongly that it should be renamed, please reopen and we can do that. The new name I considered was "TotalSumOfSquares," That is a little misleading though, because it sits in the hierarchy between the now hidden First and Third moments and carries an embedded FirstMoment.
