规则变化时间序列的簇泛函估计:滑动块估计

Estimation of cluster functionals for regularly varying time series: sliding blocks estimators

Youssouph Cissokho, Rafal Kulik

摘要:

聚类指数描述了平稳时间序列的极值行为。我们考虑他们的滑动块估计。利用现代理论的多元,经常变化的时间序列,我们得到中心极限定理的条件下,可以很容易地验证了一个大类的模型。特别是,我们表明,在峰值超过阈值的框架,滑动和不相交的块估计有相同的极限方差。

英文摘要:

Cluster indices describe extremal behaviour of stationary time series. We consider their sliding blocks estimators. Using a modern theory of multivariate, regularly varying time series, we obtain central limit theorems under conditions that can be easily verified for a large class of models. In particular, we show that in the Peak over Threshold framework, sliding and disjoint blocks estimators have the same limiting variance.
