Radiographic Applications of Receiver Operating Characteristic (ROC) Curves

Radiology, 1974
The basic concepts underlying the theory and experimental determination of receiver operating characteristic (ROC) curves are discussed. Such curves were used to describe the detectability of the image of 2 mm Lucite beads (similar to certain small gallstones) in a noisy background of radiographic mottle. Results are shown for four typical radiographic

Bifractal receiver operating characteristic curves: a formula for generating receiver operating characteristic curves in credit-scoring contexts

The Journal of Risk Model Validation, 2021
This paper formulates a mathematical model for generating receiver operating characteristic (ROC) curves without underlying data. Credit scoring practitioners know that the Gini coefficient usually drops if it is only calculated on cases above the cutoff.

The Receiver Operating Characteristic Curve

2003
Abstract In this chapter we consider medical tests with results that are not simply positive or negative, but that are measured on continuous or ordinal scales. The receiver operating characteristic (ROC) curve is currently the best-developed statistical tool for describing the performance of such tests.

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.

A Permutation Test to Compare Receiver Operating Characteristic Curves

Biometrics, 2000
Summary. We developed a permutation test in our earlier paper (Venkatraman and Begg, 1996, Biometrika83, 835–848) to test the equality of receiver operating characteristic curves based on continuous paired data. Here we extend the underlying concepts to develop a permutation test for continuous unpaired data, and we study its properties through ...

The Generalized Receiver Operating Characteristic Curve

2016
The problem is to predict whether a random outcome is a "success" (R=1) or a "failure" (R=0) given a continuous variable Z. The performance of a prediction rule $D=D(Z)\in \{1,0\}$ boils down to two probabilities, beta =Pr (D=1|R=1) and alpha =Pr (D=1|R=0). We wish beta is high, alpha is low. Given a set of rules D such that any d in D is attributed to
