Discrete Weibull-Rayleigh distribution properties and parameter estimations
Discrete Weibull-Rayleigh distribution properties and parameter estimations
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 …
