What is SpatialExtremes?
SpatialExtremes is an add-on package for the statistical
software R. Its goal is
to provides tools for the statistical modelling of spatial
extremes. Why bother about spatial extremes? The areal modelling
of the extremes of a natural process such as rainfall or
temperature is important in environmental statistics; for
example, understanding extreme areal rainfall is crucial in
flood protection. Nor the univariate neither the multivariate
extreme value theory will be useful in such situations as most
of the environmental processes are spatial in extent. This
software provides recent statistical models for spatial
extremes. The main types of statistical models thus far
implemented are based on latent variables, on copulas and on
max-stable processes.
How do I install it?
You have secveral possibilities. As SpatialExtremes is available
on CRAN you can install it directly from an R session. If you
feel more risky then you can get
the last
development version from
the r-forge
system.

Exact simulations
Exact simulations of max-stable processes are now available using the fantactic job of C. Dombry, S. Engelke and M. Oesting.

Parallelization
The package makes uses of OpenMP if available on your platform. You should have substantial CPU time gains. Well I hope...
