An inferential measure of dependence between two systems using Bayesian model comparison
Guillaume Marrelec, Alain Giron
We propose to quantify dependence between two systems and in a dataset based on the Bayesian comparison of two models: one, , of statistical independence and anoth…

Multilevel testing of constraints induced by structural equation modeling in fMRI effective connectivity analysis: A proof of concept
G. Marrelec, A. Giron
In functional MRI (fMRI), effective connectivity analysis aims at inferring the causal influences that brain regions exert on one another. A common method for this type of analysis…

Exponential decay of pairwise correlation in Gaussian graphical models with an equicorrelational one-dimensional connection pattern
Guillaume Marrelec, Alain Giron, Laura Messio
We consider Gaussian graphical models associated with an equicorrelational and one-dimensional conditional independence graph. We show that pairwise correlation decays exponentiall…
