Enhanced spatial modeling on linear networks using Gaussian Whittle-Matérn fields
Somnath Chaudhuri, Maria A. Barceló, Pablo Juan +4
Spatial statistics is traditionally based on stationary models on like Matérn fields. The adaptation of traditional spatial statistical methods, originally designed…

Wasserstein complexity penalization priors: a new class of penalizing complexity priors
David Bolin, Alexandre B. Simas, Zhen Xiong
Penalizing complexity (PC) priors provide a principled framework for reducing model complexity by penalizing the Kullback--Leibler Divergence (KLD) between a ``simple'' base model…

Leveraging population information in brain connectivity via Bayesian ICA with a novel informative prior for correlation matrices
Amanda Mejia, David Bolin, Daniel Spencer +1
Brain functional connectivity (FC), the temporal synchrony between brain networks, is essential to understand the functional organization of the brain and to identify changes due t…
