Bayesian Methodology Group

Bayesian methodology group lead by Aki Vehtari conducts research in the field of modern computational science and develops generic computational statistical methods. These include fast approximative inference methods as well as model assessment and selection methods for complex hierarchical, non-parametric, graphical, dynamic and spatio-temporal models. The developed methods can handle larger datasets using more elaborate and computationally intensive models than before while keeping the computation time reasonable to aid researchers in other scientific fields. The methods are applied to challenging scientific problems in, e.g., brain signal analysis (MEG, fMRI), epidemiology, genetics, bioinformatics, medicine, tomography, animal population research, audio signal processing, and tracking.
