The SURVEYIMPUTE Procedure

ID Statement

  • ID variable;

The ID statement names a variable in the DATA= input data set to identify observation units. When you use an OUTPUT statement, the OUT= data set includes the ID variable. PROC SURVEYIMPUTE uses the ID variable values to identify the donor observations. If you do not use an ID statement, the procedure creates a new variable named UnitID that uses the observation numbers to identify the donor observations.
