Use the text field to specify additional variables or effects by which to model the covariance structure of the response variable.
These effects typically comprise class variables and their interactions.
Caution: Do not repeat any effects here that are already specified as Fixed Threshold.
To Specify Additional Random Effects:
8
Type one or more randome effectsin the text field.
8
If you specify more than one fixed effect that you must separate the effects with spaces. For example, assuming A and B are listed as Cluster Center Variable, typing A B in the text field specifies variables A and B as main fixed effects.
8
To specify interactions between effects, type an asterisk (*) between the effects. For example, assuming A and B are listed as Cluster Center Variable, typing A B A*B specifies variables A and B, and the interaction between A and B as fixed effects, and constructs a two-way ANOVA model.
8
A vertical bar (|) can be used to create main effects and interactions. For example, typing A|B is the same as typing A B A*B.
