General Loglinear Analysis Model dialog box
Specify Model. A saturated model contains all main effects and interactions involving
factor variables. It does not contain covariate terms. Select
Custom to specify only a
subset of interactions or to specify factor-by-covariate interactions.
Factors and Covariates. The factors and covariates are listed, with (Cov) indicating a
covariate.
Terms in Model. The model depends on the nature of your data. After selecting Custom,
you can select the main effects and interactions that are of interest in your analysis. You
must indicate all of the terms to be included in the model.
Build Terms
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.
