描述----------Description----------
The package SpatialExtremes aims to provide tools for the analysis of spatial extremes. Currently, the package uses the max-stable processes framework for the modelling of spatial extremes.
的包SpatialExtremes极端的空间分析工具,旨在提供。目前,包使用的最大稳定过程的极端的空间建模框架。
Max-stable processes are the extension of the extreme value theory to random fields. Consequently, they are good candidate to the analysis of spatial extremes. The strategy used in this package is to fit max-stable processes to data using composite likelihood.
最大稳定过程的极值理论的随机领域的延伸。因此,它们是很好的候选人,极端的空间分析。在此包中所采用的策略是,以适应最大稳定过程数据,使用复合的可能性。
In the future, the package will allow for non-stationarity as well as other approaches to model spatial extremes; namely latent variable and copula based approaches.
在未来,该包将允许非平稳性以及其他方法来模拟空间的极端,即潜在变量和基于Copula方法。
A package vignette has been writen to help new users. It can be viewed, from the R console, by invoking vignette("SpatialExtremesGuide").
已经书面上的包小插曲,帮助新用户。从R控制台,它可以被看作调用vignette("SpatialExtremesGuide")。
