LIAM2 is a tool to develop (different kinds of) microsimulation models.
The goal of the project was to let modellers concentrate on what is strictly specific to their model without having to worry about the technical details. This was achieved by providing a generic microsimulation toolbox which is not tied to a particular model. By making it available for free, our hope was to greatly reduce the development costs (in terms of both time and money) of microsimulation models.
The toolbox was made as generic as possible so that it could be used to develop almost any microsimulation model as long as it used cross-sectional ageing, i.e., all individuals are simulated at the same time for one period, then for the next period, etc.
All in one bundles for the last stable LIAM2 release can still be downloaded from the releases page on GitHub. Each bundle contains the LIAM2 software, a demonstration model, and documentation.
The documentation for LIAM2 can still be found online at Read the Docs.
