CLASS Statement
- CLASS variables ;
The CLASS statement names 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.
Class levels are determined from the formatted values of the CLASS
variables. Thus, you can use formats to group values into levels.
Refer to the discussion of the FORMAT procedure in the SAS
Procedures Guide and to the discussions of the FORMAT statement
and SAS formats in SAS Language Reference: Dictionary. You can adjust
the display order of CLASS variable levels with the
ORDER= option in the PROC MIXED statement.
