Leerdoelen The student is able
1. to state and apply a taxonomy of Generalized Linear Models (GLM) in terms of measurement levels of the response, link function, design of (repeated) data collection related to the exponential family of distributions;
2. to mathematically derive and computationally implement maximum likelihood estimation of a GLM by iterative weighted least squares using the R programming environment;
3. to integrate the testing of medical/economic hypotheses to appropriate statistical model fitting as well as their selection by likelihood ratio or Akaike’s Information Criterion;
4. to evaluate the quality of model estimation in various applied scientific fields.
Omschrijving Taking the exponential family of distributions as a starting point, various generalized linear models are developed to model non-Gaussian response data. The aim is to describe this response in terms of a number of explanatory variables. Estimated models are evaluated and interpreted in order to test hypotheses from various scientific fields. In this course we will introduce estimation principles underlying generalized linear modeling. This course covers the following themes:
- Exponential family
- Maximum likelihood, Deviance, likelihood ratio
- Iterative weighted least squares
- Model Design
- Goodness of fit, residuals
- Linear, logistic (multinomial), Poisson regression, Loglinear models, Survival Analysis
