Categorical Variables Defining Groups

Specify one or more variables whose levels form distinct categories in the model.

Note: The order in which you specify these variables determines how mean values are sorted.

To Specify Variables Defining the One-Way Classification:

8

Specify the Experimental Design SAS Data Set.

The Available Variables field is populated with variables from the specified data set.

8

Left-click a single variable, or hold down Ctrl while left-clicking multiple variables, from the Available Variables field.

8

Click to add the selected variable(s) to the Variables Defining the One-Way Classification field.

In this example, observations are first grouped by line, and then by sex, and finally by age.
