Features of the Area under the Receiver Operating Characteristic (ROC) Curve. A Good Practice [PDF]

open access: yesThe Stata Journal, 2016
The area under the receiver operating characteristic (ROC) curve is a measure of discrimination ability used in diagnostic and prognostic research. The ROC plot is usually represented without additional information about decision thresholds used to generate the graph. In our article, we show that adding at least one or more informative cutoff points on

What's under the ROC? An Introduction to Receiver Operating Characteristics Curves [PDF]

open access: yesCanadian Journal of Psychiatry, 2007
It is often necessary to dichotomize a continuous scale to separate respondents into normal and abnormal groups. However, because the distributions of the scores in these 2 groups most often overlap, any cut point that is chosen will result in 2 types of errors: false negatives (that is, abnormal cases judged to be normal) and false positives (that is,

Receiver operating characteristic (ROC) curve for medical researchers

open access: yesIndian Pediatrics, 2011
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

Statistical Methodology: III. Receiver Operating Characteristic (ROC) Curves [PDF]

open access: yesAcademic Emergency Medicine, 1997
ABSTRACTMeasures including sensitivity, specificity, and positive and negative predictive values have been traditionally used to assess a diagnostic test's ability to detect the presence or absence of disease. Receiver operating characteristic (ROC) curve analysis allows visual evaluation of the trade‐offs between sensitivity and specificity associated

Modernising Receiver Operating Characteristic (ROC) Curves

open access: yesAlgorithms, 2023
The justification for making a measurement can be sought in asking what decisions are based on measurement, such as in assessing the compliance of a quality characteristic of an entity in relation to a specification limit, SL. The relative performance of testing devices and classification algorithms used in assessing compliance is often evaluated using

Characterizing the diagnostic sensitivity and specificity of pain biomarkers in cattle using receiver operating characteristic curves

open access: yesJournal of Dairy Science, 2022
: Biomarkers are used to assess pain and analgesic drug efficacy in livestock. However, often the diagnostic sensitivity and specificity of these biomarkers for different painful conditions over time have not been described.
