摘要翻译:
本文统一和推广了Hougaard、Crowder和Tawn研究的一类多元极值(EV)模型的结果。在这些模型中,无条件分布和条件分布都是EV,所有的低维边际和极大值都属于这类。这导致了理解、分析和预测的实质性经济。模型的一种解释是EV分布的尺寸混合,其中混合是正稳定分布。第二种解释是指数稳定的位置混合(对于Gumbel)或功率稳定的尺度混合(对于非Gumbel EV分布)。第三种解释是通过具有正稳定强度的峰值超过阈值模型。混合变量被用作建模工具,并用于更好地理解和模型检查。我们研究方差模型组件的极值相似,以及新的时间序列、空间和连续参数极值模型。结果被应用于点蚀调查的数据。

英文摘要:
This paper unifies and extends results on a class of multivariate Extreme Value (EV) models studied by Hougaard, Crowder, and Tawn. In these models both unconditional and conditional distributions are EV, and all lower-dimensional marginals and maxima belong to the class. This leads to substantial economies of understanding, analysis and prediction. One interpretation of the models is as size mixtures of EV distributions, where the mixing is by positive stable distributions. A second interpretation is as exponential-stable location mixtures (for Gumbel) or as power-stable scale mixtures (for non-Gumbel EV distributions). A third interpretation is through a Peaks over Thresholds model with a positive stable intensity. The mixing variables are used as a modeling tool and for better understanding and model checking. We study extreme value analogues of components of variance models, and new time series, spatial, and continuous parameter models for extreme values. The results are applied to data from a pitting corrosion investigation.
