mqriskR

mqriskR provides functions for actuarial risk modeling, including survival models, life annuities, multiple-decrement models, and mortality improvement projections, using standard actuarial notation.

The package is designed to support teaching, exam preparation, and reproducible actuarial analysis.

Installation

You can install the stable version from CRAN:

install.packages("mqriskR")

You can install the development version from GitHub:

# install.packages("remotes")
remotes::install_github("aokine/mqriskR")

Example

This example computes a whole life annuity under a uniform distribution of deaths.

library(mqriskR)

ax(40, i = 0.05, model = "uniform", omega = 100)

Features

• Life insurance and annuity functions (discrete, continuous, and m-thly)
• Survival models and mortality laws
• Multiple-decrement models
• Mortality improvement projections
• Functions aligned with standard actuarial notation

Purpose

This package is intended for:

• Actuarial students preparing for professional exams
• Instructors teaching life contingencies
• Practitioners needing transparent and reproducible calculations
