R package
- IBMPopSim, co-authored with D. Giorgi and V. Lemaire (LPSM, Sorbonne-Universite), available on the CRAN. The package simulates the random evolution of a wide range of heterogeneous population models, called stochastic Individual Based Models (IBMs), with applications in actuarial sciences, biology, demography or ecology. Documentation and examples.
Presentation at the GT ARC (december 2020, in french).
