PROC HPMIXED Class Variables
Use this field to specify those variables whose levels are to be considered nominal.
Class variables are those variables whose values define the groups for analysis. Class variables typically have a few discrete values that define the classifications of the variable. A CLASS statement is used to handle these variables.
