Обсуждение: corr() in 8.1

Is there an easy way to have the corr() statistical function in 8.1?
(I know very little about compiling things.)
Or does somebody have a custom aggregate function for that?

Thanks for the help.

Nothing that's likely to be easier than updating to 8.2 ... and given
the lack of multiple-input aggregates in 8.1, anything you did would
be a serious kluge anyway.
