Description Details References See Also

Provides functions for the selection of extreme value threshold. At the moment only the simplest case, where the data can be treated as independent identically distributed observations, is considered. Future releases will tackle more general situations. See the 'threshr' website for more information, documentation and examples.

The main function in the threshr package is `ithresh`

,
which uses leave-one-out cross-validation in a Bayesian setup to compare
the predictive ability resulting from the use of each of a user-supplied
set of thresholds.

See `vignette("threshr-vignette", package = "threshr")`

overview of the package.
