  The longevity R package provides provide maximum likelihood estimation
routine for modelling of survival data that are subject to non-informative
censoring and truncation mechanisms. It includes a selection of 12 parametric
models of varying complexity, with a focus on tools for extreme value analysis
and more specifically univariate peaks over threshold modelling. The package
comes with visual diagnostics that account for the sampling scheme for lifetime
data, utilities for univariate threshold selection, non-parametric maximum
likelihood estimation, goodness-of-fit diagnostics and model comparisons tools.
The different methods therein are illustrated using aggregated tabular data of
longevity from Japan, and truncated lifelengths Dutch records.
