ROCCONTRAST Statement
-
ROCCONTRAST <'label'> <contrast> </ options>;
The ROCCONTRAST statement compares the different ROC models. You can specify only one ROCCONTRAST statement. The ROCOPTIONS options in the PROC LOGISTIC statement control how the models are compared. You can specify one of the following contrast specifications:
If no contrast is specified, then the REFERENCE contrast with the default reference curve is used. See the section Comparing ROC Curves for more information about comparing ROC curves, and see Example 72.8 for an example.
The following options are available:
