A recipe for accurate estimation of lifespan brain trajectories, distinguishing longitudinal and cohort effects

Øystein Sørensen, Kristine Walhovd, Anders Fjell

This paper considers estimation of lifespan brain trajectories from longitudinal data, using generalized additive mixed models. It studies how to distinguish longitudinal effects from cohort effects, and shows example code in R which practitioners can use for their own data. Published in NeuroImage.
