longevity

A collection of parametric and nonparametric methods for the analysis of survival data. Parametric families implemented include Gompertz-Makeham, exponential and generalized Pareto models and extended models. The package includes an implementation of the nonparametric maximum likelihood estimator for arbitrary truncation and censoring pattern based on Turnbull (1976) doi:10.1111/j.2517-6161.1976.tb01597.x, along with graphical goodness-of-fit diagnostics. Parametric models for positive random variables and peaks over threshold models based on extreme value theory are described in Rootzén and Zholud (2017) doi:10.1007/s10687-017-0305-5; Belzile et al. (2021) doi:10.1098/rsos.202097 and Belzile et al. (2022) doi:10.1146/annurev-statistics-040120-025426.
