两种寿命分布类性质的讨论及非参数检验

Discussion of Nature and Non-parametric Test against Two Aging Notions

基于寿命分布类NBUrh(新比旧以反失效率好)和NBRUrh(新比更新旧以反失效率好),研究它们的性质,讨论它们与其他寿命分布类的关系,计算检验统计量渐近分布的P itm an’s渐近功效(PAE),并用蒙特卡罗方法模拟对应非参数检验在小样本情况下关于几种备选分布的势,以衡量检验的功效,说明该检验方法的合理性.

This paper studies the nature of relationships with other aging notions based upon aging properfies of NBUrh and NBRUrh then evaluates the PitmanS asymptotic efficiency （PAE）. The power of the test is also estimated by simulation for some alternatives when the sample size is small, to measure the effectiveness of testing and to show that the test is reasonable.
