The topics of the workshop include, but are not limited to, contingency tables, staged trees, asymptotic theory, software implementations and algebraic statistics.

It aims is to strengthen the European network of researchers working on staged trees, chain event graphs, reasoning on asymmetric independence inference and models for contingency tables.

We look forward to your participation in trees4cat. Should you have any questions, please feel free to contact us at Manuele.leonelli@ie.edu mailto:Manuele.leonelli@ie.edu.
