Yet, although both types of phenomena have been thoroughly studied in isolation, the relationships between them are not well understood. On one hand, postmortem studies, structural MRI, and resting PET studies have provided detailed information abo...
متن کاملStatistical Approaches for the Study of Cognitive and Brain Aging
Neuroimaging studies of cognitive and brain aging often yield massive datasets that create many analytic and statistical challenges. In this paper, we discuss and address several limitations in the existing work. (1) Linear models are often used to model the age effects on neuroimaging markers, which may be inadequate in capturing the potential nonlinear age effects. (2) Marginal correlations a...
