Algebraic Statistics and the Study of Multistate Models: Theory and Applications

This multidisciplinary project is funded by University of Helsinki, Aalto University and KU Leuven Seed Fund. It aims to advance novel applications of algebraic statistics within the framework of multistate models for complex time-to-event processes. There will be two workshops organized as part of this project: one in Espoo/Helsinki in spring 2025 and one in Leuven in fall 2025.

Workshop April 1-4, 2025

This workshop will be held at Aalto University and the University of Helsinki from April 1–4, 2025, bringing together experts in algebraic statistics and survival and event history analysis. The primary goal is to introduce participants to the fundamental concepts of both fields. The program includes introductory mini-courses on April 2–3, while April 1 and 4 will focus on discussions aimed at fostering connections between the two areas. This workshop is open to researchers at all levels who are interested in exploring the intersection of algebraic statistics and survival and event history analysis.
