Random Effects

Use the text field to specify random effects by which to model the covariance structure of the response variable.

Random effects are typically comprised of class variables and their interactions.

To Specify Random Effects:

Type one or more random effects in the text field.

If you specify more than one random effect, then you must separate the effects with spaces. For example, assuming A and B are listed as Class Variables, typing A B in the text field specifies variables A and B as random effects.
