Description

Recent years have seen a tremendous increase in the use and development of Bayesian methods for academic research. In its wake, more and more companies employing statisticians are valuing the knowledge brought by these approaches. The goal of this course is to give participants a brief and intensive introduction to Bayesian statistics.

Participants will learn how Bayesian inference differs from classical inference and how to interpret its results in a meaningful way. They will acquire the skills to use Bayesian techniques correctly in a range of practical applications.

Topics that will be discussed include the difference between Bayesian and frequentist/classical probability, the likelihood function, choice of prior distributions, conjugate priors, the posterior distribution and methods for summarizing the posterior. In addition, an overview will be given about the most important Markov Chain Monte Carlo Methods that are often used to simulate the posterior distribution. These methods include the Gibbs sampler, Importance sampling, Metropolis-Hastings and the Slice sampler.

Depending on the interest and background of the participants, the Bayesian estimation of one (or more) of the following approaches will be explained and discussed: linear regression, choice models (logit, probit, multinomial), Bayesian hypothesis testing, quantile regression, mixed models, Bayesian variable selection, …

All exercises in this course will use R together with the rjags R-package and the JAGS software. Note that JAGS is very similar (if not identical) to the popular BUGS/winBUGS language for Bayesian modeling.

Target audience

This course targets professionals and investigators from diverse areas who wish to get acquainted with Bayesian techniques to be able to apply them to their practical applications.

Exam

Participants can, if they wish, take part in an exam. Upon succeeding in this test a certificate from Ghent University will be issued.
The exam consists of a take home project assignment. Students are required to write a report by a set deadline.

Incorporation in DTP and reimbursement from DS for UGent PhD students

As a UGent PhD student, to be able to incorporate this course in your Doctoral Training Program (DTP) and get a reimbursement of the registration fee from your Doctoral School (DS) you need to follow strict rules: please take the necessary action in time. The deadline to open a dossier on the DS website (Application for Recognition) for this course is January 14, 2022. Please note that opening a dossier does not mean that you are enrolled. You still need to enrol via the registration form on this site.

Please note: For UGent PhD students it is no longer necessary to participate/succeed in this exam to be able to incorporate the course in the DTP.

Course prerequisites

Participants are expected to have an active knowledge of the basic principles underlying statistical strategies, at a level equivalent to Module 2 of this year's program.

Basic knowledge of the statistical programming language R is required as provided in Module 1 of this year's program.

Teacher

Foto Dries BenoitProf. dr. Dries Benoit is professor of Business Analytics at the faculty of Economics and Business Administration of Ghent University. He teaches Bayesian statistics to the Business Engineering students and in the Master of Statistical Data-Analysis.

His research is focused on the use of Bayesian statistics for business analytics. He worked on problems ranging from customer relationship management, over credit scoring to pricing and revenue management. Methodologically, he contributed to the field of Bayesian quantile regression and Bayesian robustness.
