WebJan 8, 2024 · The harmonic mean can deal with fractions with different denominators. Therefore, it is the most appropriate approach to average ratios, e.g., the P/E and EV/EBITDA ratios. Unequal denominators will cause different weights for each data when the arithmetic mean is applied. The arithmetic mean of P/E ratios is biased unless all … WebThe harmonic and geometric means are concave symmetric functions of their arguments, and hence Schur-concave, while the arithmetic mean is a linear function of its arguments, so both concave and convex.
