Eike Rathke commented on OFFICE-2387:
-------------------------------------
There are indeed several places in different functions' definitions where such a sentence is used.
Thanks for the hint about 5.2 Semantics, that makes those other places superfluous and we can remove them.

> Text under Semantics reads:
> "Implementations should be wary of actually calculating PEARSON this way, due to numerical instability issues."
> "...be wary..."? Perhaps a note, if it says what those "issues" may be.
> BTW, in researching this function I found: http://www.statemaster.com/encyclopedia/Correlational-research
> It may just be a presentation issue but does the square root on the denominator extend across both of the summation signs?
> Oh, the resource I cite above alleges a better way to calculate this function with numeric stability.
