We develop statistical algorithms to calibrate individual-based models with data, to assess their validity and to compare, select or average alternative models. These algorithms are mainly designed for Approximate Bayesian Computation (ABC). We also develop a **R package “EasyABC”** (Jabot et al. 2013) that encapsulates our various contributions (Lenormand et al. 2013, Jabot et al. 2014) and those of external contributors. These computational statistics techniques are enabling innovative works in **ecological modelling** (Bridier et al. 2014, Lagarrigues et al. 2014, Rougier et al. 2015, Jabot & Lohier 2016).
