Using the MEAN function

This script creates a SAS^© table named 'ints'. It uses the INPUT statement to read four variables (ID, X1, X2, X3) from internally provided data (DATALINES). A new variable 'mu' is calculated for each observation containing the arithmetic mean of variables X1, X2, and X3.

Data Analysis

Type : CREATION_INTERNE

The data is generated by the script itself via the DATALINES statement.
