Adjust Variability for these Random Effects

Specify random effects by which to model the covariance structure of the response variable. These are typically comprised of class variables and their interactions.

Caution: Do not repeat any effects here that are already specified as Fixed Effects.

Specify the Array effect here only if there are multiple observations on each array.
