Ordinal Regression Location Model
The Location dialog box allows you to specify the location model for your analysis.
Specify model. A main-effects model contains the covariate and factor main effects but no interaction effects. You can create a custom model to specify subsets of factor interactions or covariate interactions.
Factors/covariates. The factors and covariates are listed.
Location model. The model depends on the main effects and interaction effects that you select.
For the selected factors and covariates:
- Interaction
- Creates the highest-level interaction term of all selected variables. This is the default.
- Main effects
- Creates a main-effects term for each variable selected.
- All 2-way
- Creates all possible two-way interactions of the selected variables.
- All 3-way
- Creates all possible three-way interactions of the selected variables.
- All 4-way
- Creates all possible four-way interactions of the selected variables.
- All 5-way
- Creates all possible five-way interactions of the selected variables.
