$\mathbb{R}^d$上平稳极大稳定随机场函数的中心极限定理

A central limit theorem for functions of stationary max-stable random fields on $\mathbb{R}^d$

Erwan Koch, Clément Dombry, Christian Y. Robert

摘要:

最大稳定随机场非常适合于空间极值的统计建模。因此,给定区域上最大稳定随机场函数的积分可以在评估自然灾害风险方面发挥关键作用,这意味着它与提高我们对其概率行为的理解有关。为此,本文给出了$\mathbb{R}^d$上平稳极大稳定随机场函数的一个一般中心极限定理.然后,我们证明了具有幂变差函数的Brown-Resnick随机场和Smith随机场的适当函数满足中心极限定理。另一个强烈的动机,我们的工作在于,中心极限定理的随机场上的$\mathbb{R}^d$几乎没有考虑在文献中。作为一个应用程序,我们简要地展示了我们的结果在风险评估方面的实用性。

英文摘要:

Max-stable random fields are very appropriate for the statistical modelling of spatial extremes. Hence, integrals of functions of max-stable random fields over a given region can play a key role in the assessment of the risk of natural disasters, meaning that it is relevant to improve our understanding of their probabilistic behaviour. For this purpose, in this paper, we propose a general central limit theorem for functions of stationary max-stable random fields on $\mathbb{R}^d$. Then, we show that appropriate functions of the Brown-Resnick random field with a power variogram and of the Smith random field satisfy the central limit theorem. Another strong motivation for our work lies in the fact that central limit theorems for random fields on $\mathbb{R}^d$ have been barely considered in the literature. As an application, we briefly show the usefulness of our results in a risk assessment context.
