AUK: a simple alternative to the AUC [PDF]

open access: yes, 2010
The area under Receiver Operating Characteristic (ROC) curve, also known as the AUC-index, is commonly used for ranking the performance of data mining models. The AUC has many merits, such as objectivity and ease of interpretation.

Receiver operating characteristic curves with an indeterminacy zone

open access: yesPattern Recognition Letters, 2020
This work extends Receiver Operating Characteristic (ROC) curve to the situation where some cases, falling in an intermediate "indeterminacy zone" of the predictor, are not classified. It addresses two challenges: definition of sensitivity and specificity bounds for this case; and summarization of the large number of possibilities arising from ...

Receiver operating characteristic curves: a basic understanding. [PDF]

open access: yesRadioGraphics, 1992
Receiver operating characteristic (ROC) is one form of an objective measurement that can be used to compare newer imaging technologies against human observer performance (the ability of the expert radiologist). Use of ROC curves allows one to account for a continuum of radiologic interpretations when calculating sensitivity and specificity for an ...

On the optimism correction of the area under the receiver operating characteristic curve in logistic prediction models [PDF]

open access: yes, 2019
When the same data are used to fit a model and estimate its predictive performance, this estimate may be optimistic, and its correction is required. The aim of this work is to compare the behaviour of different methods proposed in the literature when ...

Asymptotic properties of the sequential empirical ROC, PPV and NPV curves under case-control sampling

open access: yes, 2012
The receiver operating characteristic (ROC) curve, the positive predictive value (PPV) curve and the negative predictive value (NPV) curve are three measures of performance for a continuous diagnostic biomarker.

Comparative assessment of three common algorithms for estimating the variance of the area under the nonparametric receiver operating characteristic curve [PDF]

open access: yes
The area under the receiver operating characteristic (ROC) curve is often used to summarize and compare the discriminatory accuracy of a diagnostic test or modality,and to evaluate the predictive power of statistical models for binary outcomes ...

Comparison of genotypic and phenotypic methods of metallo-β- lactamase detection in Acinetobacter spp.

open access: yesJournal of Global Infectious Diseases, 2020
Introduction: MBL containing genes have been reported in all GNBs including Acinetobacter spp since 1990s which are worrisome as they are transmitted by mobile genetic elements. Thus, early detection of MBL encoding organisms is necessary.

An Improved Method for Bandwidth Selection when Estimating ROC Curves [PDF]

open access: yes
The receiver operating characteristic (ROC) curve is used to describe the performance of a diagnostic test which classifies observations into two groups.
