VC Variance components. This is the default covariance structure for random effects.
When the variance components structure is specified on a RANDOM
subcommand, a scaled identity (ID) structure is assigned to each of the effects
specified on the subcommand. If the variance components structure is specified
on the REPEATED subcommand, it is replaced by the diagonal (DIAG)
structure.
