Class Variables

Specify all variables whose levels form distinct categories in the model , in this field.

All of the variables from the specified experimental design data set are listed in the Available Variables field.

List all variables whose levels form distinct categories in the model in the Class Variables field. Indicator variables are created for each level of each variable. If you do not specify an effect, then the numerical values of the variables are used directly in the model as in linear regression .

Note : The order in which you specify class variables determines the way LSMeans and/or interaction effects are sorted.

To Specify Class Variables:

Highlight variable(s) from the Available Variables field. To highlight multiple variables at once, hold down Ctrl while left-clicking on them.
