title: An introduction to multivariate growth curve analyses.
abstract: The Potthoff-Roy growth curve model provides a convenient and useful representation for the multivariate analysis of growth curve and repeated measurement data. In particular, it is especially well-suited for polynomial growth models, which can accurately summarize growth characteristics over limited time frames. In this paper we offer a tutorial in multivariate growth curve methodology, our aim being to assist investigators in implementing appropriate statistical analyses of growth curve data.
