Analysis of Covariance PROC MIXED, PROC GLM, Chapter 15, SAS Essentials, Alan Elliott & W Woodward

This was by far the most helpful video I watched on how to use the SAS MIXED model! Thank you so much for this!! Just curious, would you happen to also have a/some section(s) on: - the steps pre-PROC MIXED, such as checking for normality of the distribution, homoscedasticity, etc.? - factor analysis to check the internal validity of multiple items in a construct? No worries if not, but that would be beyond amazing if you have something about that as well. In any case, thanks again and kindest wishes from Canada!

This is very helpful. Thank you! I have a question about the proc glm for ANCOVA. I have a repeated data(two groups and four time measures) and the homogeneity test is violated so I'd like to adjust baseline as a covariates. Is it possible to adjust baseline using proc glm?
