Data Subsetting

Using a Simple Subsetting Statement

Often, it is necessary to perform an analysis on only a subset of the participants in the dataset.

DATA  new-dataset-name;
   SET  existing-dataset-name;
IF  comparison;

PROC  name-of-desired-statistical-procedure   DATA=new-dataset-name;
RUN;
