The EVALUATE statement causes PROC DTREE to evaluate the decision tree and calculate the optimal decisions. If the SUMMARY option is specified a decision summary is displayed. Otherwise, the current optimal value is displayed on the SAS log.

The following options, which can appear in the PROC DTREE statement, can also be specified in the EVALUATE statement:

The MAXPREC=, MAXWIDTH=, and NWIDTH=, options are valid only in conjunction with the SUMMARY option. The RT= option is valid only in conjunction with the CRITERION=MAXCE or CRITERION=MINCE specification. The options specified in this statement are only in effect for this statement.
