Categorical Variables
Specify all variables whose levels form distinct categories in the model, in this field.
List all variables whose levels form distinct categories in the model in the Categorical 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 categorical variables determines how difference tests and interaction effects are sorted.
To Specify Categorical Variables:
*
All of the variables from the specified experimental design data set are listed in the Available Variables field.
