title: Analysis of repeated measures experiments on individuals subjected to different treatments.
abstract: This article illustrates the ability of MANOVA to analyze the data of a doubly multivariate repeated measures design study using the multivariate set up. The advantage of this statistical method is to evaluate the effect of time and treatments, and their interaction on many combined dependent variables. The difference in the evolution of scores obtained by repeated measures may then be assessed statistically, thus permitting us to evaluate the longitudinal dimension of the study. This analysis allows for more global conclusions simultaneously taking into account the different aspects of the study. The limits and uses of this statistical technique are also discussed.
