BATMAN: Statistical analysis for expensive computer codes made easy

Abstract

Bayesian Analysis Tool for Modelling and uncertAinty quaNtification (batman) is an open source Python package dedicated to statistical analysis based on non-intrusive ensemble experiment. Numerical software has reached a sufficient maturity to represent physical phenomena. High fidelity simulation is possible with continuous advances in numerical methods and in High Performance Computing (HPC). Still, deterministic simulations only provide limited knowledge on a system as uncertainties in the numerical model and its inputs translate into uncertainties in the outputs. Ensemble-based methods are used to construct a numerical or experimental dataset from which statistics are inferred.
