Unlike the SUMMARY option on the PROC DTREE statement or the EVALUATE statement, which specifies that PROC DTREE display a decision summary when the decision tree is evaluated, the SUMMARY statement causes the procedure to display the summary immediately. If the decision tree has not been evaluated yet, or if it has been changed (by the MOVE, MODIFY, or RECALL statement) since last evaluated, the procedure evaluates or re-evaluates the decision tree before the summary is displayed.

The following options that can appear in the PROC DTREE statement can also be specified in this statement:

The options specified in this statement are in effect only for this statement.
