**Apologies for cross posting** Course: Introduction to graphical models and Bayesian networks for social scientists 8-9 June 2009 Roger Bannister Lecture Theatre, St Mary's Campus, Imperial College, London This 1.5 day course has two components. Day 1 covers the basics of graphical models, also known as causal diagrams, focusing on directed acyclic graphs. Day 2 is a half-day introduction to Bayesian networks and expert systems with Hugin software which used graphical models to inform decision making processes. The lecturers are Dr Sara Geneletti of the Imperial College department of Epidemiology and Public Health and the BIAS II project funded by the National Centre for Research Methods, and Dr Gianluca Baio of University College London department of Epidemiology and Public Health. Day 1: Diagrams are often used to express belief about the relationships between variables in complex problems. By formulating such diagrams as graphical models and in particular directed acyclic graphs (DAGs) it is possible to formalise these diagrams and use them for statistical and causal inference. Also, by representing complex problems using DAGs it is possible to build a bridge between researchers in different fields. Day 2: We cover the basics of Bayesian inference, with specific reference to social sciences and its relationships and possible applications with the technology of Probabilistic Expert Systems (Bayesian Networks). The main general issues are discussed in a tutorial form with worked examples in Hugin, one of the main computer softwares used in the field. This course is aimed at introducing graphical modelling concepts to social scientists with a basic understanding of statistical methods (e.g. hypothesis testing, regression).
