- Categorical response
- Select this check box to analyze a dependent (criterion) variable that is categorical in nature, i.e., to perform a classification analysis. When this check box is selected, the Response codes button on the Quick tab will become active, provided you have specified a dependent variable. Note that if this check box is not selected, even the categorical response variable selected for the analysis will be treated as a continuous response variable. Likewise, if the selected dependent variable is continuous and the Categorical response check box is selected, the dependent variable will be treated as categorical.
