The course includes correlation as well as simple and multiple linear regression analysis, with application to medical and psychological areas. In particular, the following topics are being covered:

• Model selection  procedures
• Interaction and confounding
• Regression diagnostics
• Transformation of variables
• Fractional polynomial regression
• Regression splines
• Power analysis
• Implementation of these techniques in statistical software packages

PhD students, master students at a Medical Student Research Program, or holders of a Norwegian master´s degree of five years or 3+ 2 years (or equivalent) may be admitted.

be able to

• identify different types of explanatory variables and correctly implement them in a linear regression model.

• interpret the results from linear regression models.
• evaluate whether the assumptions of the regression models are fulfilled.
• calculate power and sample size in linear models

have the general ability to
