The HPSAMPLE Procedure

Syntax: HPSAMPLE Procedure

The following statements are available in the HPSAMPLE procedure:

PROC HPSAMPLE <options> ;
VAR variable <variable ... variable> ;
CLASS variable <variable ... variable> ;
TARGET variable <variable ... variable> ;

Either a VAR or a CLASS statement is required for simple random sampling; both the CLASS and TARGET statements are required for stratified sampling.
