In SAS, the "repeated" statement specifies a compound symmetry (CS) covariance structure, where the correlations between measurements are the same regardless of time point. In R, this is specified using corCompSymm() in the correlation argument of lme(). 2. In SAS, the "subject" is specified as person, meaning the random intercepts and CS correlations are modeled at the person level. In R, this is spec
