Can anyone tell me what the following error means?
WARNING: The R matrix depends on observation order within subjects. Omitting observations from the analysis because of missing values can affect this matrix. Consider using a classification effect in the RANDOM _RESIDUAL_ statement to determine ordering in the R matrix.
I am attempting to run repeated measures on some data. The design was 20 animals blocked into light and heavy bodyweights, then assigned to 1 of 2 treatments withing each block. The animals had biopsies at 5 time points and gene expression was measured on 8 genes at each point. Attached is the SAS input as well as the output. I am not sure my denominator DF are correct and this may be associated with the error? Any help would be greatly appreciated.
