PROC ACECLUS
PROPORTION=p THRESHOLD=t <options> ;
The PROC ACECLUS statement invokes the ACECLUS procedure. Table 23.2 summarizes the options available in the PROC ACECLUS statement. These options are also discussed in the following sections. Note that, if you specify the METHOD=COUNT option, you must specify either the PROPORTION= or the MPAIRS= option. Otherwise, you must specify either the PROPORTION= or THRESHOLD= option.
