The BOXPLOT Procedure

ID Statement

  • ID variables;

The ID statement specifies variables used to identify observations. The ID variables must be variables in the input data set.

If you specify the keyword SCHEMATICID or SCHEMATICIDFAR with the BOXSTYLE= option, the value of an ID variable is used to label each extreme observation. When you specify a BOX= data set, the label values come from the variable _ID_, if it is present in the data set. When you specify a DATA= or HISTORY= input data set, or a BOX= data set that does not contain the variable _ID_, the labels come from the first variable listed in the ID statement. If ID statement is specified, the outliers are not labeled.
