Laurent Gardes, Stéphane Girard

AI总结:

本文针对Weibull尾系数估计问题,提出一类新估计量及相应极端分位数估计量,建立渐近正态性并比较渐近均方误差,通过有限样本情形验证了理论结果。

摘要:

我们研究Weibull尾系数的估计问题,该系数是逆失效率函数的正则变化指数。我们提出了一类该系数的估计量以及一个相应的极端分位数估计量。建立了它们的渐近正态性,并比较了它们的渐近均方误差。结果在一些有限样本情形下进行了说明。

英文摘要:

We address the problem of estimating the Weibull tail-coefficient which is the regular variation exponent of the inverse failure rate function. We propose a family of estimators of this coefficient and an associate extreme quantile estimator. Their asymptotic normality are established and their asymptotic mean-square errors are compared. The results are illustrated on some finite sample situations.
