Abstract
In this paper, a new distribution is introduced based on a continuous
Weibull-Rayleigh distribution, that is a new three-parameter lifetime
model called as the discrete Weibull-Rayleigh distribution. It is a
distribution allowing for a bathtub-shaped hazard rate function. Its
mathematical properties are discussed, and the estimation of model
parameters is compared by the maximum likelihood and the least square
methods. An actual data set of thermal aging is fitted to the new model,
which shows the superiority of the proposed distribution.
