Can anyone help or provide resources for
help with the following mixed model analysis questions
in SAS proc mixed?
1. Understanding when specifications for the random
and repeated statements for repeated measures designs
result in confounding of certain variance components.
SAS System for Mixed Models provides a couple of examples.
Are there other places that I could look? In particular,
I'm looking for the situation when the design is a split
plot with whole plots blocked and repeated measures taken
on the whole plots.
2. In a split plot design, with levels of factor A assigned
to whole plots, with whole plots blocked, and repeated
measures over time on the whole plots, including or not
including the block x time interaction in the
random statement. In most examples of split plot design analysis
in proc mixed that I see, this term is omitted.
Thanks for any help.
