Subject: Equivalent of covariance pattern model with a heterogeneous compound symmetric
Hi everyone,
I am trying to figure out how to replicate the results I've gotten from SPSS when using the Repeated Covariance Type : Compound Symmetry: Heterogeneous. Can anyone help me figure this out?
So far I know the following does't produce the same results.
comsym <- gls(SC_slope~Bodysite+Pattern+Strength,data = df.na.removed.,
correlation=corCompSymm(form = ~ 1 |id), method="REML", na.action = na.omit)
summary(comsym)
