I just made a short test, to prove my solutions in a mathematic corse. But The
Covariance (http://en.wikipedia.org/wiki/Sample_mean_and_sample_covariance) is
not right calculated in my oppinion....

OOo calc seems to use 1/n to multiply the sum, but correct is 1/(n-1). This
difference is big when I only use a few data....
