About

Maintained by Paul J. NorthropCRAN page ↗GitHub ↗Website ↗Issues ↗

Performs adjusted inferences based on model objects fitted, using maximum likelihood estimation, by the extreme value analysis packages 'eva' https://cran.r-project.org/package=eva, 'evd' https://cran.r-project.org/package=evd, 'evir' https://cran.r-project.org/package=evir, 'extRemes' https://cran.r-project.org/package=extRemes, 'fExtremes' https://cran.r-project.org/package=fExtremes, 'ismev' https://cran.r-project.org/package=ismev, 'mev' https://cran.r-project.org/package=mev, 'POT' https://cran.r-project.org/package=POT and 'texmex' https://cran.r-project.org/package=texmex. Adjusted standard errors and an adjusted loglikelihood are provided, using the 'chandwich' package https://cran.r-project.org/package=chandwich and the object-oriented features of the 'sandwich' package https://cran.r-project.org/package=sandwich. The adjustment is based on a robust sandwich estimator of the parameter covariance matrix, based on the methodology in Chandler and Bate (2007) doi:10.1093/biomet/asm015. This can be used for cluster correlated data when interest lies in the parameters of the marginal distributions, or for performing inferences that are robust to certain types of model misspecification. Univariate extreme value models, including regression models, are supported.

Changes in 1.2.4

Bug fixes

Updates to methods for mev::fit.egp() to comply with versions 2.0 and add new models.
Add Details, Value and Examples sections in logLik.logLikVec.Rd and logLikVec.Rd to avoid CRAN HTML validation NOTE on r-devel Debian.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("lax", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("paulnorthrop/lax")

Development version from paulnorthrop/lax. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-lax

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-lax

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-lax

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
