Dear Guillaume,
Dear Amir,
Thanks a lot for your emails and very interesting comments! In "A Sensitivity Analysis of fMRI Balloon Model" a block design dataset was used, and not the SPM's balloon model, so I am wondering whether the findings are relevant for the case of an event-related design and the SPM's balloon model (what I am interested in). "Modeling the hemodynamic response to brain activation" did not investigate the impact of the priors on the results, but this is what "Robust Inference with Variational Bayes" deals with in a more general way. Anyway, I have to read these papers more carefully! Thanks for help!
Best wishes,
Wiktor Olszowy
