Summary of INSET Keywords :: SAS/QC(R) 12.1 User's Guide

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 17.123 shows an inset containing entries from a DATA= data set.

You can use the keywords in Table 17.87 only when producing ODS Graphics output. Greek letters are used in the labels for the statistics requested with the UMU and USIGMA keywords.

Keyword	Description
TESTLEGEND	requests a legend of positive tests for special causes
UMU	estimated or specified process mean
USIGMA	estimated or specified process standard deviation
