DOI: 10.1002/sim.9222
Abstract: It is common to compare biomarkers' diagnostic or prognostic performance using some summary ROC measures such as the area under the ROC curve (AUC) or the Youden index. We propose to compare two paired biomarkers… read more here.

Abstract: With great interest, we read the study by Wilcox et. al. “The limits of small‐for‐gestational‐age as a high‐risk category” [1], which showed that small‐for‐gestational age (SGA) was a poor marker for predicting neonatal mortality and… read more here.

DOI: 10.1080/10543406.2018.1535502
Abstract: ABSTRACT In medical diagnostic research, medical tests with continuous values are widely employed to distinguish between diseased and non-diseased subjects. The diagnostic accuracy of a medical test can be assessed by using the receiver operating… read more here.

DOI: 10.1080/10543406.2020.1832107
Abstract: ABSTRACT In medical diagnostic studies, the Youden index is a summary measure widely used in the evaluation of the diagnostic accuracy of a medical test. When covariates are not considered, the diagnostic accuracy of the… read more here.

DOI: 10.1111/biom.12686
Abstract: A novel nonparametric regression model is developed for evaluating the covariate-specific accuracy of a continuous biological marker. Accurately screening diseased from nondiseased individuals and correctly diagnosing disease stage are critically important to health care on… read more here.

DOI: 10.1177/0962280217742538
Abstract: The three-class Youden index serves both as a measure of medical test accuracy and a criterion to choose the optimal pair of cutoff values for classifying subjects into three ordinal disease categories (e.g. no disease,… read more here.
