Bayesian graphical modelling It is a powerful methodology for visualizing and analyzing complex epidemiological data,it is ideally suited for risk factor studies and analysis of questionnaire data. This technique may reveal far more about complex disease systems than standard approaches when dealing with many inter-related variables, as is common in farm survey data.
Workshop It is largely computer based and uses R. Some familiarity with R would be advantageous but not essential, as would previous experience of basic epidemiology and statistical modelling, such as linear regression techniques. Instructor Dr Fraser Lewis is an Applied Statistician in the Section of Epidemiology, Vetsuisse. Fraser has over 10 years experience working with epidemiological data following degrees in Statistics and a PhD in Mathematics. He has recently received funding from the Swiss National Science Foundation to develop Bayesian network models for applications in epidemiological research, in collaboration with the Farm Surveillance Unit within the Public Health Agency of Canada.
Date, Venue and Registration The workshop will be held on 15-17 February at the Camden Campus of The University of Sydney (425 Werombi Road, Camden NSW 2570).
This course is being run on a cost-recovery basis. The course fee is $150 for students and $300 for non-students. This fee includes the course materials, morning and afternoon tea/coffee and lunch for each day.
