Topics Covered

• Gene-environment interaction in the development of human traits, including disease
• Conceptual and analytical challenges
• Joint analysis of data on both genetic and environmental factors from epidemiologic studies as a way to increase power to detect a polymorphism (or an exposure) that is associated with disease risk
• Study designs
• Statistical modeling issues in the analysis of data
• Sample size and power calculations for a range of designs
• Specification of parameters
• Ordinal coding
• Hierarchical models
• The analysis of highdimensional "pathway" data (multiple related genes and environmental exposures)
