Clustering-Based Inter-Regional Correlation Estimation
Hanâ Lbath, Alexander Petersen, Wendy Meiring +1
A novel non-parametric estimator of the correlation between grouped measurements of a quantity is proposed in the presence of noise. This work is primarily motivated by functional…
A Mixed Model Approach for Estimating Regional Functional Connectivity from Voxel-level BOLD Signals
Ruobin Liu, Chao Zhang, Chau Tran +3
Resting-state brain functional connectivity quantifies the synchrony between activity patterns of different brain regions. In functional magnetic resonance imaging, each region com…
Nodal statistics-based equivalence relation for graph collections
Lucrezia Carboni, Michel Dojat, Sophie Achard
Node role explainability in complex networks is very difficult, yet is crucial in different application domains such as social science, neurosciences or computer science. Many effo…
Local Whittle estimation with (quasi-)analytic wavelets
Sophie Achard, Irène Gannaz
In the general setting of long-memory multivariate time series, the long-memory characteristics are defined by two components. The long-memory parameters describe the autocorrelati…
Inter-regional correlation estimators for functional magnetic resonance imaging
Sophie Achard, Jean-Francois Coeurjolly, Pierre Lafaye de Micheaux +1
Functional magnetic resonance imaging (fMRI) functional connectivity between brain regions is often computed using parcellations defined by functional or structural atlases. Typica…
Asymptotic control of FWER under Gaussian assumption: application to correlation tests
Sophie Achard, Pierre Borgnat, Irène Gannaz
In many applications, hypothesis testing is based on an asymptotic distribution of statistics. The aim of this paper is to clarify and extend multiple correction procedures when th…
