基于聚类的时间序列极值推断

Cluster based inference for extremes of time series

Holger Drees, Anja Janßen, Sebastian Neblung

摘要:

本文提出了一种新的正则变化时间序列谱尾过程的估计方法。该方法是基于一个特征的谱尾过程,这是纳入新的估计通过投影技术的不变性。我们证明了该估计的一致渐近正态性,在已知和未知的情况下,定期变化的指数。在模拟研究中,新的程序显示出比以前提出的估计更稳定的性能。

英文摘要:

We introduce a new type of estimator for the spectral tail process of a regularly varying time series. The approach is based on a characterizing invariance property of the spectral tail process, which is incorporated into the new estimator via a projection technique. We show uniform asymptotic normality of this estimator, both in the case of known and of unknown index of regular variation. In a simulation study the new procedure shows a more stable performance than previously proposed estimators.
