Hi,

Now MATH384 should soon be ready to be closed, too. I will commit in
2.2 and trunk when somebody (Phil?) has had the time to review the
patch proposals.

Cheers, Mikkel.

>> Right now the DescriptiveStatistics is for ResizableDoubleArray, but if =

there is no way of doing this (besides the inefficient way of creating a Re=
sizableDoubleArray from the double[]).

>> Idea: Create a DescriptiveStatistics for double[] also. I'm not sure whi=
ch way of implementing it would be the best, but one way would be to make D=
escriptiveStatistics abstract with all but the apply-method implemented as =
now. The apply-method should be made as abstract which then has to implemen=
ted in the extensions together with a field containing the values. (addValu=
e, windowSize etc. has to go in the ResizableDoubleArray-extension.) The do=
uble[]-extension should then have a constructor taking double[] as a parame=
ter.
