Following the recommendations of the reviewers of the initial RTG proposal, we have also strengthened the role of statistics and introduced for the third cohort the new research area R4 Statistics with the principal investigators Prof. Dr. Werner Brannath, Prof. Dr. Thorsten Dickhaus and Prof. Dr. Vanessa Didelez.
Research area R4 analyses statistical approaches to parameter identification problems. Modern statistical research centres around high-dimensional, complex structured data, which often exhibit strong (spatial, temporal, spatio-temporal, or causal) dependencies. This poses challenges for the modelling and for the inference steps of statistical data analysis. In particular, high-dimensional parameter spaces require proper regularisation techniques as well as sophisticated algorithms and computer implementations for statistical estimation, testing, and model selection procedures. These aspects are reflected and addressed in all projects of this research area.
