Pre-conference online course

Topic: Graphical Models and Bayesian Networks (with R)

Date and time:

June 3, 2021 (11.00 – 16:00, Helsinki time) and June 4, 2021 (11.00-14.00, Helsinki time)

Instructor: Søren Højsgaard, Department of Mathematical Sciences, Aalborg University, Denmark

Goals:

  • Graphical models as a framework for modelling associations in multivariate data.
  • Dependency graphs and conditional independence restrictions – the components of graphical models.
  • Evidence synthesis and probability propagation with Bayesian networks (BNs) using the gRain package.
  • A look under the hood of BNs to understand mechanisms of probability propagation.
  • Learning BNs from data using the bnlearn package.
  • Learning BNs from data using graphical log-linear models in the gRim package.
  • Some classical models viewed from a graphical models perspective

Prerequisites:

A working understanding of log-linear models for contingency tables will be very helpful. R will be used for illustration and exercises.
