Class Level Information

If you use a CLASS statement to name classification variables, PROC SURVEYREG  displays a "Class Level Information" table. This table contains the following information for each classification variable:

• Class Variable, which lists each CLASS variable name

• Levels, which is the number of values or levels of the classification variable

• Values, which lists the values of the classification variable. The values are separated by a white space character; therefore, to avoid confusion, you should not include a white space character within a classification variable value.
