DMCEN is a versatile index regarding sensitivity (capability of each class-model to contain its own objects) and specificity (capability of the each class-model to reject foreign objects). DMCEN develops the idea that a classification model introduces an order in the objects of a dataset, capable of being measured by the decrease in entropy that it entails. A detailed description of the algorithm and its properties for evaluating a k-class-model with respect to other indexes can be seen at: O. Valencia M.C. Ortiz, M.S. Sánchez, L.A.
