> From a post on 9 Oct, 2012 to [email protected] from Peter Andrews

> I have implemented a version of OneWayAnova which uses SummaryStatistics
> rather than requiring the array of doubles.
> I know that there is a whole process for submitting code but I am under a
> deadline so sending this email with the code is all I am going to do.
> A couple of notes:
> I would have maintained the same signature structure simply adding
> methods that supported Collection<SummaryStatistics> but that creates an
> error because it has the same Signature due to type erasure on
> Collection<double[]>.
> I did not see why certain cases such as having only one array or number
> of elements < 2 should necessarily throw exceptions -- the math still works
> out and gives reasonable results so given point #1, I differentiated the
> function signatures by adding a boolean to optionally skip the checks and
> therefore not not throw DimensionMismatchException.
> Minor note: I understand that you cannot change it at this point but there is
> no reason for this class not to abstract with static methods since it has no
> state.
> Do with this what you will.
> Thanks for the wonderful tools you provide.
