The New Poisson Exponential Power Distribution for Lifetime Modeling
Aref Khanjari Idenak , Mohammadreza Zadkarami, Alireza Daneshkhah
Abstract:   (20083 Views)
In this paper a new compounding distribution with increasing, decreasing, bathtub shaped and unimodal-bathtub shaped hazard rate function. The new three-parameters distribution as a generalization of the exponential power distribution is proposed. Maximum likelihood estimation of the parameters, raw-moments, density function of the order statistics, survival function, hazard rate function, mean residual lifetime, reliability function and median are presented. Then the properties of this distribution are illustrated based on a real data set.
Keywords: Exponential power distribution, Hazard rate, Lifetime model, Survival function
