Technical Note Mixed-effect statistics for group analysis in fMRI: A nonparametric maximum likelihood approach
TL;DR: In this article, a collection of test statistics accounting for estimation uncertainties at the within-subject level, that can be used as alternatives to the standard t statistic in one-sample random-effect analyses, is presented.
Proceedings Article
Fast clustering for scalable statistical analysis on structured images
TL;DR: In this article, a linear-time clustering scheme was proposed for brain images, which bypasses the percolation issues inherent in these algorithms and thus provides compressions nearly as good as traditional quadratic-complexity variance-minimizing clustering schemes.

TL;DR: To facilitate statistical analysis of small cohorts, a sparse discriminant model is used that selects predictive voxels on the reference task and thus provides a principled procedure to define ROIs and it is shown that voxel selection based on transfer learning leads to higher detection power on small cohorts.
Variable Importance on Medical Images and Socio-Demographic Data
TL;DR: HAL as discussed by the authors is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not, which may come from teaching and research institutions in France or abroad, or from public or private research centers.
New Results - Accurate Definition of Brain Regions Position Through the Functional Landmark Approach
TL;DR: A fast functional landmark detection procedure, that explicitly models the spatial variability of activation foci in the observed population is introduced, and it is demonstrated that explicit functional landmark modeling approaches are more effective than standard statistical mapping for brain functional focus detection.
