Statistical extreme value modelling of threshold excesses, maxima
and multivariate extremes. Univariate models for threshold excesses and maxima
are the Generalised Pareto, and Generalised Extreme Value model respectively.
These models may be fitted by using maximum (optionally penalised-)likelihood,
or Bayesian estimation, and both classes of models may be fitted with covariates
in any/all model parameters. Model diagnostics support the fitting process.
Graphical output for visualising fitted models and return level estimates is
provided. For serially dependent sequences, the intervals declustering algorithm
of Ferro and Segers (2003)
Extreme value modelling with R. Includes univariate modelling using generalized Pareto, generalized extreme value, Weibull and Gumbel distributions, and the multivariate conditional approach of Heffernan and Tawn.
The package contains a test suite that depends on the testthat package. To use the test suite, install using 'R CMD INSTALL --install-tests' and then running 'devtools::test("texmex")' within R, where "texmex" points to the package location.
