and covariates specifiedin the main dialog box. Alternatively,you can build a custom model that

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.
All3-way. Createsall possible three-way interactions of the selected variables.
All4-way. Createsall possible four-way interactions of the selected variables.
All5-way. Createsall possible five-way interactions of the selected variables.
