%description
An interface to the 'BaM' (Bayesian Modeling) engine, a 'Fortran'-based
executable aimed at estimating a model with a Bayesian approach and using
it for prediction, with a particular focus on uncertainty quantification.
Classes are defined for the various building blocks of 'BaM' inference
(model, data, error models, Markov Chain Monte Carlo (MCMC) samplers,
predictions). The typical usage is as follows: (1) specify the model to be
estimated; (2) specify the inference setting (dataset, parameters, error
models...); (3) perform Bayesian-MCMC inference; (4) read, analyse and use
MCMC samples; (5) perform prediction experiments. Technical details are
available (in French) in Renard (2017)
