(2004) to identify clusters of individual longitudinal\ntrajectories. The procedure involves (1) calculating 24\nmeasures describing the features of the trajectories; (2) using\nfactor analysis to select a subset of the 24 measures and (3)\nusing cluster analysis to identify clusters of trajectories,\nand classify each individual trajectory in one of the clusters.", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "Roxygen": "list(markdown = TRUE)",
