Comparing the SAS® GLM and MIXED Procedures for Repeated Measurements Analysis
Russ Wolfinger and Ming Chang, SUGI Proceedings, 1995


Repeated measures analyses in the GLM procedure involve the traditional univariate and multivariate approaches. The 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.
