The HPCLUS Procedure

The ID statement lists one or more variables from the input data set that are transferred to the scored output data set, provided that the output data set produces one (or more) records per input observation. When you specify the OUT= option in the SCORE= statement, the ID variables, followed by the _CLUSTER_ID_ variable and the _DISTANCE_ variable, are added to the output data set that is specified in OUT= option. By default, the HPCLUS procedure does not transfer any variables from the input data set to the output data set. The ID statement accepts numeric and character variables. The variables in an ID statement can appear in any INPUT statement.
