The following example shows the HPFDIAGNOSE procedure with the default settings. The data sets AAA, BBB, and CCC are not specific data sets.

   proc hpfdiag data=aaa print=all;
      id date interval=month;
      forecast y;
   run;

The HPFDIAGNOSE procedure always performs the intermittency test first. If the HPFDIAGNOSE procedure determines that the series is intermittent, then the preceding example is equivalent to the following statements:

   proc hpfdiag data=aaa print=all;
      id date interval=month;
      forecast y;
      idm intermittent=2 base=auto;
   run;

However, if the HPFDIAGNOSE procedure determines that the series is not intermittent, then the default settings are equivalent to the following statements:

   proc hpfdiag data=aaa print=all siglevel=0.05
                criterion=rmse holdout=0 holdoutpct=0 prefilter=yes
                back=0 errorcontrol=(severity=all stage=all);
      id date interval=month;
      forecast y;
      transform type=none;
      trend dif=auto sdif=auto;
      arimax method=minic p=(0:5)(0:2) q=(0:5)(0:2) perror=(5:10)
         outlier=(detect=maybe maxnum=2 maxpct=2
                  siglevel=0.01 filter=full);
      esm method=best;
   run;
