The input variables can be either continuous or categorical.
You must specify the following LEVEL= option:
LEVEL=INTERVAL | NOMINAL
specifies whether the specified input variables are continuous or categorical. You can specify the following values:
INTERVAL
specifies that the input variables are continuous.
NOMINAL
specifies that the input variables are categorical.
For categorical variables, you can also specify the following option.
ORDER=ordering
ensures that the categorical input values are levelized in the specified order. (If you specify this option for continuous variables, the option is ignored.) You can specify one of the following values for ordering:
ASC | ASCENDING
levelizes values in ascending order.
DESC | DESCENDING
levelizes values in descending order.
FMTASC | ASCFORMATTED
levelizes values in ascending order of the formatted value.
FMTDESC | DESFORMATTED
levelizes values in descending order of the formatted value.
By default, ORDER=ASCENDING for categorical variables.
