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). This is an effective method for assessing the performance of a diagnostic test. The aim of this… 

FINDING THE OPTIMAL THRESHOLD OF A PARAMETRIC ROC CURVE UNDER A CONTINUOUS DIAGNOSTIC MEASUREMENT

• The accuracy of a binary diagnostic test can easily be assessed by comparing the sensitivity and specificity with the status of respondents. When the result of a diagnostic test is continuous, the

TLDR
The ultimate aim of this article is to provide the basic conceptual framework and interpretation of various diagnostic test indices, ROC analysis, comparison of diagnostic accuracy of different tests, and the reliability of a test so that the clinicians can use it effectively.

Receiver Operating Characteristic (ROC) Curve Analysis for Medical Diagnostic Test Evaluation.

TLDR
This review provides the basic principle and rational for ROC analysis of rating and continuous diagnostic test results versus a gold standard and the methods of estimate and testing of AUC and its testing in single diagnostic test and also comparative studies.

The choice of methods in determining the optimal cut-off value for quantitative diagnostic test evaluation

TLDR
Compared to the obtained data from binormal model and equal variances, the optimal cut-off values derived from Youden’s index, Euclidean index, and product method were similar but the diagnostic odds ratio yielded either extremely low or extremely high optimal cut off value.

Comparison of Two or More Correlated AUCs in Paired Sample Design

Purpose of study Methods of comparing the accuracy of diagnostic tests are of increasing necessity in biomedical science. When a test result is measured on a continuous scale, an assessment of the

  • Computer Science
  • 2018
TLDR
This study provides a procedure for testing for the difference in sensitivities of two or more binary classifiers over a set of cut-offs without reference to their specificities and test results show that the two were statistically difference.

A conditional approach for the receiver operating characteristic curve construction to evaluate diagnostic test performance in a family-matched case–control design

TLDR
The proposed approach will use information about correlation among biomarker values, producing conditional receiver operating characteristic curves that evaluate the ability of a biomarker to discriminate between affected and unaffected subjects in a familial paired design.

Estimation and Comparison of Receiver Operating Characteristic Curves

TLDR
This work uses a unified framework by representing the ROC curve as the distribution of the marker in cases where it has standardized it to the control reference distribution, and calculates nonparametric, semiparametric, and parametric estimators.

Comparing the areas under two or more correlated receiver operating characteristic curves: a nonparametric approach.

TLDR
A nonparametric approach to the analysis of areas under correlated ROC curves is presented, by using the theory on generalized U-statistics to generate an estimated covariance matrix.

TLDR
For a wide range of distributions, concern about bias or imprecision of the estimates of the AUC should not be a major factor in choosing between the nonparametric and parametric approaches.
