    Résumé

    These lectures will give a short introduction to the fundamentals of Bayesian inference and its application to simple but representative problems. Numerical methods such as Markov Chain Monte Carlo will be introduced and their practical workings illustrated. The Bayesian approach to model selection via Bayesian model comparison will be explained and contrasted with Frequentist hypothesis testing.
