I like all the stats function that Numbers has, but it's missing one thing. Under "Covariance", the formula in there is for population covariance, not sample covariance - the only difference between the two is that the denominator of the equation is "N" for population but "n-1" for sample. Is there a way that I can add that function to Numbers, and/or augment the name for "Covariance" in there now to say "Population" in it? I've tried looking through the package contents, but I'm not sure...
