Abstract

We solve the comparison problem for Bajraktarević-type ψ-estimators introduced by Barczy and Páles in 2022. Namely, we derive several necessary and sufficient conditions under which a Bajraktarević-type ψ-estimator is less than or equal to another Bajraktarević-type ψ-estimator for any sample. We also solve the corresponding equality problem. As an important particular case, we obtain the solutions of the two problems in question for quasi-arithmetic-type ψ-estimators.
