%description
Assists actuaries and other insurance modellers in pricing, reserving and
capital modelling for non-life insurance and reinsurance modelling.
Provides functions that help model excess levels, capping and pure
Incurred but not reported claims (pure IBNR). Includes capped mean,
exposure curves and increased limit factor curves (ILFs) for LogNormal,
Gamma, Pareto, Sliced LogNormal-Pareto and Sliced Gamma-Pareto
distributions. Includes mean, probability density function (pdf),
cumulative probability function (cdf) and inverse cumulative probability
function for Sliced LogNormal-Pareto and Sliced Gamma-Pareto
distributions. Includes calculating pure IBNR exposure with LogNormal and
Gamma distribution for reporting delay. Includes three 'shiny' tools: a
claims simulator with reinsurance structures, a generalised linear model
fitting tool, and a claims frequency and severity distribution fitting
tool. Methods used in the package refer to Free for All by Yiannis Parizas
