> What isn't so obvious is that this generalizes to the other kinds of means, like geometric. It's obvious if you realize that the geometric mean is just exp(mean(log(values))) and the harmonic mean is just 1/mean(1/values), where "mean" is the arithmetic mean (i.e. they are just the arithmetic mean performed in a transformed space). |
