mqriskR

mqriskR provides a comprehensive collection of functions for actuarial mathematics and life contingency modeling. It supports actuarial present values, premiums, reserves, pensions, multiple-life models, multiple-decrement models, mortality improvement, and both life table and parametric survival model calculations using standard actuarial notation.

The package is designed to support actuarial education, professional exam preparation, research, and reproducible actuarial analysis.

Installation

Install the stable release from CRAN:

install.packages("mqriskR")

Or install the development version from GitHub:

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

Example

Compute the actuarial present value of a whole life annuity under a uniform distribution of deaths.

library(mqriskR)

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

Main Features

• Life insurance present values
• Life annuities (discrete, continuous, and m-thly)
• Premium calculations
• Policy reserve calculations
• Pension mathematics
• Survival probabilities
• Multiple-life models
• Multiple-decrement models
• Mortality improvement projections
• Spot interest rate models
• Variable interest models
• Support for both life tables and parametric survival models
• Functions using standard actuarial notation

Version 0.1.1

Version 0.1.1 focuses on improving the quality, consistency, and usability of the package.

Highlights include:

• Improved support for life table objects
• Expanded vectorized input support
• Improved handling of finite life tables
• More consistent behavior across related functions
• Cleaner, descriptive documentation
• Improved examples and package manual
• Enhanced input validation and error handling

No breaking changes were introduced. Existing code written for earlier versions of mqriskR continues to work.

Intended Audience

The package is intended for:

• Actuarial students preparing for professional examinations
• University instructors teaching actuarial mathematics
• Researchers developing actuarial methods
• Practicing actuaries requiring transparent and reproducible calculations
