Specify Model Effects. By default, the procedure builds a main-effects model using the factors and covariates specified in the main dialog box. Alternatively, you can build a custom model that includes interaction effects and nested terms.
Non-Nested Terms
For the selected factors and covariates:
Interaction. Creates the highest-level interaction term for all selected variables.
Main effects. Creates a main-effects term for each variable selected.
All 2-way.Creates all possible two-way interactions of the selected variables.
