The GENSELECT Procedure

CLASS Statement

CLASS variable <(options)> <variable <(options)>> </ global-options>;

The CLASS statement names the classification variables to be used as explanatory variables in the analysis. You can list the response variable for binary models in the CLASS statement, but this is not required. Table 7.2 summarizes the values that you can use for either an option or a global-option. The options are fully documented in the section CLASS Statement in Chapter 3: Shared Concepts.

Table 7.2: CLASS Statement Options

Option	Description
DESCENDING	Reverses the sort order
MISSING	Treats missing values as valid levels
ORDER=	Specifies the sort order for the levels
PARAM=	Specifies the parameterization of the variable
REF=	Specifies the reference level of the variable
SPLIT	Allows design columns for a variable to enter or leave the model independently
