摘要
通过对连续的Weibull-Pareto分布进行离散,得到了三参数离散Weibull-Pareto分布.离散Weibull-Pareto分布的失效率函数具有单调和浴盆形状.得到了离散Weibull-Pareto分布参数的极大似然估计和最小二乘估计.通过真实算例说明离散Weibull-Pareto分布在实际应用中的有效性.
A three-parameter discrete Weibull-Pareto distribution is introduced based on a discrete analogue of the continuous Weibull-Pareto distribution.The discrete Weibull-Pareto distribution is flexible,has monotonous and bathtub shaped hazard rate functions.The maximum likelihood and the least square of the discrete Weibull-Pareto distribution are derived as estimations.The effectiveness of discrete Weibull-Pareto distribution in practical applications is illustrated by real examples.
