is an introductory course about Bayesian inference and Bayesian
modelling for data analysis. We will balance between theoretical and
analytical tools and practice. In particular for practical
implementation of Bayesian models on real data we will make use of some
software for Bayesian modelling and inference (R, BUGS/JAGS, INLA).

In this course we will cover:

  • Introduction to Bayesian Thinking
    In this part we will
    cover basic definitions, Bayesian model, Bayes’ theorem. Subjective
    prior elicitation and some noninformative or default prior choices (e.g.
    Jeffreys’Rule). Conjugate analysis. Techniques and tools for
    characterizing and summarizing posterior distributions. Bayes Factor, introduction to multi-model inference and Bayesian model choice.

  • Multiparameter Inference
    In this part we will cover
    multivariate normal and multinomial models and introduces to approximate
    random sampling from a multivariate distribution. Bayesian inference in
    the presence of missing data.

  • MC & MCMC
    Introduction to Monte Carlo and Monte
    Carlo Markov Chain sampling techniques for approximating expectations
    and distributions: Gibbs Sampling and Metropolis Hastings algorithms.
