The ANOM Procedure


ID Statement

In addition, you can optionally specify the following statement:

  • ID variables;

The ID statement specifies variables used to identify observations. The ID variables must be variables in the DATA= or SUMMARY= input data sets.

The ID variables are used in the following ways:

  • If you create an OUTSUMMARY= or OUTTABLE= data set, the ID variables are included. If the input data set is a DATA= data set, only the values of the ID variables from the first observation in each group are passed to the output data set.

  • If you specify the TABLEID or TABLEALL options in a chart statement, the table produced is augmented by a column for each of the ID variables. Only the values of the ID variables from the first observation in each group are tabulated.

  • If you specify the BOXSTYLE= SCHEMATICID option or the BOXSTYLE= SCHEMATICIDFAR option in the BOXCHART statement, the value of the first variable listed in the ID statement is used to label each extreme observation.
