Plot multiple receiver-operator characteristics (ROC) curves to make comparisons between them.
Select a cell in the dataset.
On the Analyse-it ribbon tab, in the
Statistical Analyses group, click Diagnostic, and then under the Accuracy heading, click:
|Compare ROC Curves
||Compare 2 or more independent ROC curves.
|Compare Correlated ROC Curves
||Compare 2 or more paired/correlated ROC curves.
The analysis task pane opens.
In the True state drop-down list, select the true condition variable.
In the Positive event drop-down list, select the state that indicates the presence of the condition/event of interest.
If comparing 2 or more independent ROC curves, in the Y drop-down list, select the diagnostic test variable, and then in the Factor drop-down list, select the grouping variable.
If comparing 2 or more paired/correlated ROC curves, in the Y list, select the diagnostic test variables.
