to compare the sensitivity, specificity and area under the ROC curve (AUC) of indices constructed using equal number of …, specificity and AUC of an index increase as the number of partitions of components increases. However, the rate that the … regression model for each component was proposed as potential weight. The current simulation results showed that the sensitivity …

In several cases the same measurement is used as a marker for two or more population features, and it is useful to test whether this measurement has the same diagnostic effectiveness with respect to different features. In this paper we use the area under receiver operating characteristic curve...
