Subject [jira] Commented: (MATH-173) One-way ANOVA
Date Sat, 26 Jan 2008 22:52:34 GMT

    [ https://issues.apache.org/jira/browse/MATH-173?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12562934#action_12562934
] 

Phil Steitz commented on MATH-173:
----------------------------------

Slightly modified version of the second patch applied in r615531.

* Renamed to OneWayAnova, OneWayAnovaImpl
* Made inner class in impl static
* Moved R code to anovaTestCases in /test/R 

Still remaining 
* User Guide update
* Add to TestUtils

The sums of squares are computed "naively" in this implementation (just following definitional
forumulas).  I am OK releasing initial version like this, but would welcome patches that improve
numerics (as in Variance)

Will resolve after community review and items above are completed.
