Summary of INSET Keywords

INSET and INSET2 Statements

Summary of INSET Keywords

All keywords available with the SHEWHART procedure's INSET and INSET2 statements request a single statistic in an inset, except for the NTESTS, NTESTS2 and DATA= keywords. The NTESTS and NTESTS2 keywords each require a list of indexes specifying the tests for special causes whose counts of positive results are to be displayed:

   inset ntests 1 2 3 4;
   inset ntests2 1 to 4;

For each of the requested tests, the number of positive results for the test is displayed in the inset. So if tests 1 through 4 are requested the results occupy four lines in the inset.

The DATA= keyword specifies a SAS data set containing (label, value) pairs to be displayed in an inset. The data set must contain the variables _LABEL_ and _VALUE_. _LABEL_ is a character variable whose values provide labels for inset entries. _VALUE_ can be character or numeric, and provides values displayed in the inset. The label and value from each observation in the DATA= data set occupy one line in the inset. Figure 45.3 shows an inset containing entries from a DATA= data set.
