Creating a Test Table

The test table is used during model validation by the Dynamic Lift report. You can create a test table by taking a sampling of rows from the original train table, updated train table, or any model validation table that is set aside at model training time. This DATA step randomly selects approximately 25% of the train table to create the test table:
data hmeqtabl.test;
  set hmeqtabl.train;
  if ranuni(1234) < 0.25;
run;
