> Right now the DescriptiveStatistics is for ResizableDoubleArray, but if the
> user has the double[] data she wishes to get DescriptiveStatistics for there
> is no way of doing this (besides the inefficient way of creating a
> ResizableDoubleArray from the double[]).
> It would be possible to use StatUtils, but it does not contain near as much
> functionality as DescriptiveStatistics.
> Idea: Create a DescriptiveStatistics for double[] also. I'm not sure which
> way of implementing it would be the best, but one way would be to make
> DescriptiveStatistics abstract with all but the apply-method implemented as
> now. The apply-method should be made as abstract which then has to
> implemented in the extensions together with a field containing the values.
> (addValue, windowSize etc. has to go in the ResizableDoubleArray-extension.)
> The double[]-extension should then have a constructor taking double[] as a
> parameter.
