The 15th International Multilevel Conference will be held on April 14-15, 2026.
The conference will be about all aspects of statistical multilevel analysis: innovative applications, theory, software, and methodology. The conference will be in an informal style, with much room for discussion. It will be held in the city centre of Utrecht, within a quarter hour walk or a five-minute bus ride from the Central railway station.
Keynote speakers include prof. dr. Hedeker on two-stage mixed-effects location scale models for intensive longitudinal data and prof. dr. Bürkner on probabilistic amortized Bayesian inference for multilevel models.
Abstract submission
Deadlines for submitting an abstract: If you submit before the 5th of January (2026), you will be notified before the 12th of January if your abstract is accepted. If you submit before the 23rd of February (2026), you will be notified before the 9th of March if your abstract is accepted.
This edition of the conference will also have the option for researchers working with empirical data to submit posters with questions about their analyses or sampling design. During the conference, you will have the opportunity to receive feedback on your (ongoing) research.
Young Researcher Award
The abstracts of four PhD students will be selected, and these PhD students will be invited to present their work in a special symposium. The best presentation will be awarded during the closing ceremony with the ‘Best PhD Multilevel Presentation Award’ and their conference fee will be reimbursed.
Pre and Post-conference workshops
There will be two workshop opportunities this year! Prof. dr. Hedeker will be teaching a pre-conference workshop on modeling ILD data with (mixed-effects location scale) multilevel models and prof. dr. Bürkner will teach a post-conference workshop on using the brms R package to fit Bayesian generalized (non-)linear multilevel models. More details on these workshops will be coming soon.
