Actuarial Functions and Heavy Tailed Distributions R package actuar version 3.3-7 CRAN Task View: ActuarialScience (https://CRAN.R-project.org/view=ActuarialScience) CRAN Task View: Distributions (https://CRAN.R-project.org/view=Distributions) CRAN Task View: Finance (https://CRAN.R-project.org/view=Finance) Functions and data sets for actuarial science: modeling of loss distributions; risk theory and ruin theory; simulation of compound models, discrete mixtures and compound hierarchical models; credibility theory. Support for many additional probability distributions to model insurance loss size and frequency: 23 continuous heavy tailed distributions; the Poisson-inverse Gaussian discrete distribution; zero-truncated and zero-modified extensions of the standard discrete distributions. Support for phase-type distributions commonly used to compute ruin probabilities. Main reference: <doi:10.18637/jss.v025.i07>. Implementation of the Feller-Pareto family of distributions: <doi:10.18637/jss.v103.i06>.
