The HPIMPUTE Procedure

Example 7.2 Running Client Data on the SAS Appliance

This example uses the same data set as in Example 7.1.

When the input data set resides on the client and a PERFORMANCE statement that includes a NODES= option is specified, as in the following statements, PROC HPIMPUTE copies the data set to the SAS appliance, where the imputation is performed:

 /*Perform the computation on the SAS appliance using 2 nodes*/
 option set=GRIDHOST="&GRIDHOST";
 option set=GRIDINSTALLLOC="&GRIDINSTALLLOC";
 proc hpimpute data=sampsio.hmeq out=out2;
     input mortdue value clage debtinc; 
     impute mortdue / value  = 70000;
     impute value   / method = mean;
     impute clage   / method = random;
     impute debtinc / method = pmedian; 
     performance nodes=2 details
     host="&GRIDHOST" install="&GRIDINSTALLLOC";
 run;

Output 7.2.1 shows the imputation results.
