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.
