The SURVEYREG Procedure

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.
