Modeling Alzheimer's disease: Bayesian copula graphical model from demographic, cognitive, and neuroimaging data.

ABSTRACT: BackgroundThe early detection of Alzheimer's disease (AD) requires an understanding of the relationships between a wide range of features. Conditional independencies and partial correlations are suitable measures for these relationships, because they can identify the effects of confounding and mediating variables.ObjectiveTo estimate conditional dependencies and partial correlations between relevant features in AD using a Bayesian approach to Gaussian copula graphical models (GCGMs). This approach has two key advantages. First, it includes binary, discrete, and continuous variables. Second, it quantifies the uncertainty of the estimates. Despite these advantages, Bayesian GCGMs have not been applied to AD research yet.MethodsWe design a GCGM to find the conditional dependencies and partial
