Latent trajectory studies: the basics, how to interpret the results, and what to report [PDF]

open access: yesEuropean Journal of Psychotraumatology, 2015
Background: In statistics, tools have been developed to estimate individual change over time. Also, the existence of latent trajectories, where individuals are captured by trajectories that are unobserved (latent), can be evaluated (Muthén & Muthén, 2000)
