Libraries

The following is a list of the lifelib libraries. indicates that the models in the library are built with it. These models can be transformed to self-contained Python packages independent of modelx using modelx’s export feature.

Generic Liability Models

The libraries in this category provide projection models of generic life insurance products, assuming no specific market or regulation. They are meant to be customized and extended by the user, and range from minimal cashflow models suitable for learning and validation to a comprehensive model designed for practical use.

Library		Contents
The annuallife Library		Annual projection model of basic traditional life policies
The basiclife Library		Basic life insurance cashflow models and examples
The savings Library		Cashflow models of saving products with cash values
The appliedlife Library		Comprehensive and practical projection model

Reference Liability Models

The libraries in this category provide reference liability cashflow models of the individual life and annuity products sold in a specific market. Each product comes with the product specification and technical notes that its model was built from, and the model reproduces the worked example in the notes, asserted cell by cell.

Library		Contents
The uslib Library		U.S. life and annuity reference products and models
The uklib Library		UK life and pension annuity reference products and models
The jplib Library		Japanese life and third-sector reference products and models

Miscellaneous Models

The libraries in this category cover areas other than liability cashflow projection, such as asset portfolios, economic scenario generation, IFRS 17 reporting and model point selection by cluster analysis.

Library		Contents
The assets Library		Basic models of bond portfolios
The ifrs17a library		IFRS17 calculation model and examples
The economic Library		Basic Hull-White model
The economic_curves library		Algorithms for modeling economic scenarios
The cluster Library		Notebooks for model point selection by cluster analysis

Past Libraries

The libraries listed below were introduced before the release of lifelib v0.1.1 and were originally referred to as “projects.” All of these libraries, with the exception of simithwilson, were developed using an older cashflow model. All the projects use modelx.

Library		Contents
Project fastlife		Faster reimplementation of the simplelife model
Project simplelife		Annual projection model of basic traditional life policies
Project nestedlife		Nested projections based on the simplelife model
Project ifrs17sim		Simulation of IFRS17 financial statements
Project solvency2		Life risk calculation based on the Solvency II standard formula
Project smithwilson		Extrapolation of risk-free rates by the Smith-Wilson method
