Discrete Weibull-Rayleigh distribution properties and parameter estimations

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