Admission requirements
Basic statistics and a good notion of regression models.
Description
The aims are to introduce the Bayesian philosophy and terminology and to contrast it with the
frequentist approach. The course provides a review of the most important numerical techniques, which are useful to arrive at a Bayesian solution. Also, students are taught how to use Bayesian software to model complex data. The Bayesian approach is introduced and contrasted to the frequentist approach both from an historical perspective as from a methodological viewpoint. The Bayesian interpretation of probability is treated, including subjective, conjugate and non-informative prior distributions. Bayesian concepts like posterior mean, median, credible interval are introduced and illustrated using e.g. 1stBayes. Modern Bayesian Data analysis requires highly sophisticated and very computer intensive methods. Two Markov Chain Monte Carlo (MCMC) techniques: Gibbs and Metropolis-Hastings sampling with its adaptive variants will be covered. The background of these approaches will be explained and exemplified using a variety of examples. Convergence diagnostics and convergence acceleration are important for the practical feasibility of the MCMC approaches and they will be treated in detail. The important class of hierarchical models (including repeated measurements studies, multi-level models, cluster-randomized trials, etc.) will be reviewed in a Bayesian context. A variety of medical, epidemiological and clinical trials studies will be used for illustrative purposes.
Course objectives
After the course you can tell about the key issues in Bayesian data analysis and are able to set up and analyze some basic Bayesian models.
Mode of Instruction
This course is a combination of lectures, problem sessions and computer practicals using FirstBayes, R, and WinBugs/OpenBugs.

Registration
Enroll in Blackboard for the course materials and course updates.
To be able to obtain a grade and the ECTS for the course, sign up for the (re-)exam in uSis ten calendar days before the actual (re-)exam will take place. Note, the student is expected to participate actively in all activities of the program and therefore uses and registers for the first exam opportunity.
