Term: Group-Based Trajectory Model
Last Updated: 2015-01-29
Group-based trajectory models are a statistical regression method used to identify subgroups of cases - in Chateau et al. (2015), these are physicians - who share statistically similar trajectories over time on a criterion variable (Nagin, 1999).
In Chateau et al. (2015), that variable is quality indicator trigger rates.
