Receiver Operator Characteristic (ROC) Curves

Infection Control & Hospital Epidemiology, 1988
The goal of diagnostic testing is to identify patients with a particular disease. Often, it is just as important that the test not mistakenly identify healthy persons as having disease. For example, a new test for the acquired immunodeficiency syndrome (AIDS) might identify 99.99% of all patients infected with the human immunodeficiency virus (HIV ...

Peirce, Youden, and Receiver Operating Characteristic Curves [PDF]

open access: possibleThe American Statistician, 2007
In 1884 Charles Sanders Peirce introduced two measures for evaluating predictions of a binary outcome, “the science of the method” and the “utility of the method.” In modern terminology, the former corresponds to the Youden index and the latter corresponds to the expected utility. The maximum of each measure is a commonly used criterion for the optimal

Relationship of Predictive Modeling to Receiver Operating Characteristics

Journal of Cardiopulmonary Rehabilitation and Prevention, 2008
Discriminatory capabilities of a measurement technique can be assessed by a receiver operating characteristic (ROC) curve analysis (specifically, area under the curve [AUC]) and predictive modeling (predictive accuracy and positive predictive value). Theoretically, predictive accuracy is dependent on disease prevalence while AUC assessments are not.To ...

Understanding receiver operating characteristic (ROC) curves

CJEM, 2006
In this issue of the Journal, Auer and colleagues conclude that serum levels of neuron-specific enolase (NSE), a biochemical marker of ischemic brain injury, may have clinical utility for the prediction of survival to hospital discharge in patients experiencing the return of spontaneous circulation following at least 5 minutes of cardiopulmonary ...

Receiver Operating Characteristic Analysis of Diagnostic Skill

Medical Care, 1983
In an effort to assess diagnostic skill, the authors collected estimates of the probability of positive results for 392 chest x-rays and 595 throat cultures from 56 pediatricians at different stages in training. Positivity rates were 28.6% for x-rays and 32.9% for throat cultures.

Confidence Bands for Receiver Operating Characteristic Curves

Medical Decision Making, 1993
Receiver operating characteristic (ROC) curves are mapped out by the two types of errors that are generated by varying the decision threshold used to determine which subjects will be considered abnormal. Under the conventional binormal model for the ROC curve, two- sided and one-sided simultaneous confidence bands for an entire ROC curve, or for a ...

Comparison of the Receiver Operating Characteristic for Messages Received by Ear and by Eye

The Journal of the Acoustical Society of America, 1959
Receivers were presented with equal-length words under two conditions of difficult reception: (1) by ear, against a background of white noise; and (2) by eye, for a brief period in a tachistoscope. For each word presented, the receiver recorded a message and, immediately following, gave a confidence rating with respect to his accuracy of reception. The

Receiver Operating Characteristic Curves and Their Use in Radiology

Radiology, 2003
Sensitivity and specificity are the basic measures of accuracy of a diagnostic test; however, they depend on the cut point used to define "positive" and "negative" test results. As the cut point shifts, sensitivity and specificity shift. The receiver operating characteristic (ROC) curve is a plot of the sensitivity of a test versus its false-positive ...

How to read a receiver operating characteristic curve

BMJ, 2015
Researchers investigated the use of vital signs as a screening test to identify brain lesions in patients with impaired consciousness. The setting was an emergency department in Japan. In total, 529 consecutive patients presenting with impaired consciousness, as assessed by a score of less than 15 on the Glasgow coma scale, were studied.

Receiver Operating Characteristic (ROC) Analysis

2009
Receiver Operating Characteristic (ROC curves) have been used for years in decision making from signals, such as radar or radiology. Basically they plot the hit rate versus the false alarm rate. They were introduced recently in data mining and machine learning to take into account different misclassification costs, or to deal with skewed class ...
