A COMPARISON OF ALTERNATIVE APPROACHES TO THE ANALYSIS OF MULTIVARIATE REPEATED-MEASURES DESIGNS

The analysis of the data obtained from a multivariate repeated measure s design, generally, it is accomplished across through of doubly multi variate model (MDM) analysis, or also by means of multivariate mixed m odel (MMM) analysis. Based on the examination of the Type I error rate s and power of the referred procedures, the present investigation puts of relief, on the one hand, the superiority of MDM approach of the sa mple size is very small and, on the other hand, the poor functioning s ome of the correction factors used to construct ajusted MMM tests, as for example suggested it in the routine MANOVA of the popular program SPSS.
