Recurrence relations for moments of Progressively Type-II Censored from Weibull-Rayleigh distribution and its characterizations

Abstract

This paper is devoted to get new recurrence relations satisfied by the single and product moments based on Progressively Type-II Censored (ProgT-II) from the three parameters Weibull-Rayleigh distribution (WRD) and doubly truncated WRD. Finally characterizations of the WRD based on these recurrence relations, hazard rate function and truncated moments are discussed.
