What is Lehmer Mean?
The Lehmer mean, named after Derrick Henry Lehmer, is a generalization of the weighted power mean. Unlike the power mean which uses the same power in numerator and denominator, the Lehmer mean uses consecutive powers. It provides another way to interpolate between different types of means by varying the parameter p.
Formula
Lp = Sum(x^p) / Sum(x^(p-1))
The Lehmer mean is a weighted mean where each value is weighted by x^(p-1).
