I find the new doc string for np.var a bit misleading:
"The mean is normally calculated as x.sum() / N, where N = len(x). If, however, ddof is specified, the divisor N - ddof is used instead."
This seems to refer to the divisor of the mean not of the variance.
Yes, the "mean" as used in the variance formula given in the prior sentence. I don't really like the phrasing much, either, but I inherited it from what was already there. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
