A developmental trajectory describes the course of a behavior over age or time. This lecture will provide an overview of a group-based method for analyzing developmental trajectories. The method provides the capability to (1) identify rather than assume distinctive groups of trajectories, (2) estimate the proportion of the population following each such trajectory group, (3) relate group membership probability to individual characteristics and circumstances, (4) relate trajectories to subsequent outcomes, and (5) analyze the interconnection of trajectories of different behaviors. The lecture will be followed by a workshop that demonstrates the use of a Stata plugin for estimating group-based trajectory models. For the workshop please bring your laptop w/Stata with the proc traj plugin installed.
