Receiver operating characteristic (ROC) curve for medical researchers.
Sensitivity and specificity are two components that measure the inherent validity of a diagnostic test for dichotomous outcomes against a gold standard. Receiver operating characteristic (ROC) curve is the plot that depicts the trade-off between the sensitivity and (1-specificity) across a series of cut-off points when the diagnostic test is continuous or on ordinal scale (minimum 5 categories)...
متن کاملReceiver Operating Characteristic (ROC) Curve Analysis for Medical Diagnostic Test Evaluation
This review provides the basic principle and rational for ROC analysis of rating and continuous diagnostic test results versus a gold standard. Derived indexes of accuracy, in particular area under the curve (AUC) has a meaningful interpretation for disease classification from healthy subjects. The methods of estimate of AUC and its testing in single diagnostic test and also comparative studies...
متن کاملReceiver Operating Characteristic ( ROC ) Curves
Assessment of predictive accuracy is a critical aspect of evaluating and comparing models, algorithms or technologies that produce the predictions. In the field of medical diagnosis, receiver operating characteristic (ROC) curves have become the standard tool for this purpose and its use is becoming increasingly common in other fields such as finance, atmospheric science and machine learning. T...
متن کاملStandard Setting: the application of the Receiver Operating Characteristic method
Medical teachers must not only continue to accommodate and assimilate constant changes in medical knowledge, they must also assimilate new approaches to assess both students’ declarative knowledge and procedural skills. Medical schools, postgraduate training programs and licensing bodies (e.g. the General Medical Council) must provide and oversee valid and reliable assessments for students’ com...
متن کاملApplication of Receiver Operating Characteristic Curve for Pipeline Reliability Analysis
Structural reliability analysis of buried pipeline systems is one of the fundamental issues for water and wastewater asset managers. Measuring the accuracy of a reliability analysis or a failure prediction technique is an effective approach to enhancing its applicability and provides guidance on selection of reliability or failure prediction methods. The determination of threshold value for a p...
متن کاملRisk assessment and receiver operating characteristic curves.
Risk assessment is now regarded as a necessary competence in psychiatry. The area under the curve (AUC) statistic of the receiver operating characteristic curve is increasingly offered as the main evidence for accuracy of risk assessment instruments. But, even a highly statistically significant AUC is of limited value in clinical practice.
