This year's "International Workshop on Statistical Modelling" took place in Limerick, Ireland. In addition to many interesting contributions, members of our department presented their current research results and discussed them with an international audience of experts.


We especially congratulate Johannes Brachem from the Chair of Statistics at the University of Göttingen for the award for the "Best Student Talk"!


Quentin Seiferts presented his work on flexible regression using neural networks. The strengths of (semi-)parametric regression and neural networks were combined and emphasised in three different applications.


Alexandra Daub showed her adaptive step lengths in component-wise gradient boosting in a three-parameter distribution. As an application, the number of antenatal care visits in Nigeria has been modelled.


Lars Kniepers contribution Spatially aware gradient boosting towards sparser models focusses on the fair integration of spatial effects in gradient boosting. His approach has been illustrated in an application for predicting coffee harvests.


Poster contributions of


Tobias Hepp: Sparse spatial pattern selection via component-wise gradient boosting


Marisa Lange: Distributional Regression for Lungfunction of Cystic Fibrosis Patients with a Special Focus on Spatial and Random Effects


Sophie Potts: Joint Models for rare events


were represented.
