MRSETS Subcommand (CTABLES command)

 /MRSETS COUNTDUPLICATES= {NO }
                          {YES}

For multiple response sets that combine multiple category variables, a respondent can select the same response for more than one of the variables. Typically, only one response is desired. For example, $MAGS can combine MAG1 to MAG5 to record which magazines a respondent reads regularly. If a respondent indicated the same magazine for MAG1 and MAG2, you would not want to count that magazine twice. However, if $CARS combines CAR1 to CAR5 to indicate which cars a respondent owns now, and a respondent owns two cars of the same make, you might want to count both responses. The MRSETS subcommand allows you to specify whether duplicates are counted. By default, duplicates are not counted.

The MRSETS specification applies only to RESPONSES and percentages based on RESPONSES. MRSETS does not affect counts, which always ignore duplicates.
