The Institute of Statistics is organizing a Symposium in honor of our late head of the institute, supervisor, colleague and friend Friedrich "Fritz" Leisch who passed away in April 2024 after a serious illness.

We will hear scientific research contributions from colleagues and fellow researchers on topics in statistics and computing Fritz has contributed to, such as for example clustering and mixture models, as well as literate programming and reproducible research.

During the symposium we will present the first Fritz Leisch Award winner.

Thursday 24th to Friday 25th of April 2025
