The SIM2D Procedure
ID Statement
ID variable ;
The ID statement specifies which variable to include for identification of the observations in the labels and tool tips of the OBSERVATIONS plot and the tool tips of the SIM plot. The ID statement has an effect only when you perform conditional simulation.
In the SIM2D procedure you can specify only one ID variable in the ID statement. If no ID statement is given, then PROC SIM2D uses the observation number in the plots.
