Análise de variância multivariada aplicada a dados com medidas repetidas

Abstract

In some situations, in the process of analysis of data, the interest exists to analyze the performance of some variable jointly, and to determine the influence or the importance of each changeable in presence of excessively. For this, the techniques of multivariate analysis are used. When, in particular, this interest is in identifying to the existence of effect between treatments and/or conditions of evaluation and, to verify the existence of interaction between these factors; the job of an analysis of multivariate variance is appropriate, or still, an analysis of profiles of averages; that are methods multivariate applied in the analysis of data with repeated measures and longitudinal data. The present work has for objective to develop a material of theoretician-practical support for all those that will have interest in applying the techniques above cited. For its development an ample revision of literature was carried through that congregated the main aspects of these methodologies. After this revision, developed some instructions on the necessary operational procedures for the execution of these techniques in Statistica software. With this work, one provided the users to it of statistical techniques, a basic referencial on the use and applications of the multivariate analysis, particularly, the techniques of multivariate analysis of variance and analysis of profiles of averages.
