Learning Outcomes
Knowledge
Upon successfully completing this course, students will be familiar with:
• Simple and multiple linear models applied to medical data (linear, logistic, Poisson, Cox)
• Assumptions and conditions that should be met for the application of these models
• The goodness of fit test to evaluate the performance of the models
• The necessary conditions that must exist in order to qualify as one or more variables as confounding in a relationship of outcome and exposure
• The concept of effect modification, and how it differs from confounding
• The usefulness of multiple regression techniques to analyze the relationship of an exposure to a predictive variable in the possible presence of confounding factors by using adjusted analysis
• Sample size calculation for multivariable models
Capacities
The course participants upon completion will be able to:
• Have a methodology in order to build appropriate multivariable linear models
• Investigate the existence of confounding or effect modification in medical research and manage them appropriately
• Interpretation of the results obtained from the corresponding models
• Using the fast-growing and evolving R software as a tool for statistical analysis and the creation of elegant graphs
