SpecifyModel Effects. By default, the procedure buildsa main-effectsmodel using the factors
and covariates specifiedin the main dialog box. Alternatively,you can build a custom model that
includes interaction effectsand nested terms.
Non-Nested Terms
For the selected factors and covariates:
Interaction. Creates the highest-level interactionterm for all selected variables.
Maineffects. Creates a main-effectsterm for each variable selected.
All2-way. Createsall possible two-way interactions of the selected variables.
