The HPSAMPLE Procedure

Example 9.1 Running PROC HPSAMPLE on the Client

This example demonstrates how to use PROC HPSAMPLE to perform simple random sampling on the Sampsio.Hmeq data set, which resides on the client.

When the input data set resides on the client and no PERFORMANCE statement is specified, as in the following statements, the client performs all computations:

 /*sampsio is a libref for a data source on the client.*/
 proc hpsample data=sampsio.hmeq out=out1 sampobs=20 seed=13579;
     class job reason;
     var loan value delinq derog;
 run;
 proc print data=out1;
 run;
