Invited comment on Alonzo, T. A. and Nakas, C. T. (2007). Comparison of ROC umbrella volumes with an application to the assessment of lung cancer diagnostic markers. Biometrical Journal 49 , 654–664. The umbrella volume, proposed as a parameter for diagnostic validity in a specific three group situation might be difficult to interpret in clinical applications. It should be used very cautiously.
