Actuarial Computation

Actuarial computation deals with quantifying and redistributing risk in insurance and finance. Risks refer to financial losses and may relate to health, cars, life, and financial investments, etc. Risks are redistributed by grouping many individuals and analyzing the whole group to determine premiums and risk probabilities, etc.  The Wolfram Language provides extensive support for models, data, and computation related to finance, probability, and statistics. In life insurance, important aspects include time value of money with either deterministic or stochastic models of lifetimes. In non-life insurance, important parts include the frequency and size of claims for a group, either short term or long term.
