Structural covariance networks across the life span, from 6 to 94 years of age [PDF]
Network Neuroscience, 2017 Structural covariance examines covariation of gray matter morphology between brain regions and across individuals. Despite significant interest in the influence of age on structural covariance patterns, no study to date has provided a complete life span ...

Connectivity Alterations in Vascular Parkinsonism: A Structural Covariance Study
Applied Sciences, 2022 This study aimed to investigate the structural covariance between the striatum and large-scale brain regions in patients with vascular parkinsonism (VP) compared to Parkinson’s disease (PD) and control subjects, and then explore the relationship between ...

Structural covariance and cortical reorganization in schizophrenia: a MRI-based morphometric study [PDF]
, 2018 Background: In patients with schizophrenia, distributed abnormalities are observed in grey matter volume. A recent hypothesis posits that these distributed changes are indicative of a plastic reorganization process occurring in response to a functional ...

Covariance structure estimation with Laplace approximation
Journal of Multivariate Analysis, 2023 Gaussian covariance graph model is a popular model in revealing underlying dependency structures among random variables. A Bayesian approach to the estimation of covariance structures uses priors that force zeros on some off-diagonal entries of covariance matrices and put a positive definite constraint on matrices.

Covariance matrix estimation with heterogeneous samples [PDF]
, 2008 We consider the problem of estimating the covariance matrix Mp of an observation vector, using heterogeneous training samples, i.e., samples whose covariance matrices are not exactly Mp.
