CLASS Statement

The GENMOD Procedure

CLASS Statement

CLASS variables ;

The CLASS statement specifies the classification variables to be used in the analysis. If the CLASS statement is used, it must appear before the MODEL statement.

Classification variables can be either character or numeric. The procedure uses only the first 16 characters of a character variable value.

By default, class levels are determined from the formatted values of the CLASS variables. Refer to the chapter titled "The FORMAT Procedure" in the SAS Procedures Guide and the discussion of the FORMAT statement and SAS formats in SAS Language Reference: Dictionary. Different sort orders for CLASS variables can be requested by the ORDER= option in the PROC GENMOD statement.
