Invariant Means, Complementary Averages of Means, and a Characterization of the Beta-Type Means

open access: yesMathematics, 2020
We prove that whenever the selfmapping (M1,…,Mp):Ip→Ip, (p∈N and Mi-s are p-variable means on the interval I) is invariant with respect to some continuous and strictly monotone mean K:Ip→I then for every nonempty subset S⊆{1,…,p} there exists a uniquely ...

On Arnold–Villasenor Conjectures for ˜ Characterizing Exponential Distribution Based on Sample of Size Three

open access: yesRevstat Statistical Journal, 2020
Arnold and Villase˜nor [4] obtain a series of characterizations of the exponential distribution based on random samples of size two. These results were already applied in constructing goodness-of-fit tests in [7].
