Efficient Bayesian Estimation of Dynamic Structural Equation Models via State Space Marginalization
Øystein Sørensen
Dynamic structural equation models (DSEMs) combine time-series modeling of within-person processes with hierarchical modeling of between-person differences and differences between…
MUSTER: Longitudinal Deformable Registration by Composition of Consecutive Deformations
Edvard O. S. Grødem, Donatas Sederevičius, Esten H. Leonardsen +7
Longitudinal imaging allows for the study of structural changes over time. One approach to detecting such changes is by non-linear image registration. This study introduces Multi-S…
Longitudinal modeling of age-dependent latent traits with generalized additive latent and mixed models
Øystein Sørensen, Anders M. Fjell, Kristine B. Walhovd
We present generalized additive latent and mixed models (GALAMMs) for analysis of clustered data with responses and latent variables depending smoothly on observed variables. A sca…
A recipe for accurate estimation of lifespan brain trajectories, distinguishing longitudinal and cohort effects
Øystein Sørensen, Kristine B Walhovd, Anders M Fjell
We address the problem of estimating how different parts of the brain develop and change throughout the lifespan, and how these trajectories are affected by genetic and environment…
