Repeated measures analyses in the SAS GLM procedure involve the traditional univariate and multivariate approaches. The SAS MIXED procedure employs a more general covariance structure approach. This paper compares the two procedures and helps you understand their methodologies. A numerical example illustrates many of the key similarities and differences.
