  • K {\displaystyle K} denotes lifetime morbid risk, h L 2 {\displaystyle h_{L}^{2}} denotes heritability of liability, A U C {\displaystyle AUC} denotes area under the ROC curve. (wikipedia.org)
  • The index is represented graphically as the height above the chance line, and it is also equivalent to the Area under the Curve subtended by a single operating point. (wikipedia.org)
  • analysis
  • The discriminative capacity of the 2 assays was comparable, even if total-anti-HBc performed better than IgM-anti-HBc (p = 0.212 and p = 0.062 for ROC analysis a and b respectively). (nih.gov)
  • ROC analysis provides tools to select possibly optimal models and to discard suboptimal ones independently from (and prior to specifying) the cost context or the class distribution. (wikipedia.org)
  • ROC analysis is related in a direct and natural way to cost/benefit analysis of diagnostic decision making. (wikipedia.org)
  • ROC analysis since then has been used in medicine, radiology, biometrics, forecasting of natural hazards, meteorology, model performance assessment, and other areas for many decades and is increasingly used in machine learning and data mining research. (wikipedia.org)
  • ROCCET's ROC curve generation and analysis is specifically tailored for metabolomics datasets. (wikipedia.org)
  • In the multivariate module one can choose between three different techniques - SVM (support vector machine), PLS-DA (partial least squares discriminant analysis) and Random Forests for classifying and selecting metabolites or clinical variables for an optimal ROC performance. (wikipedia.org)
  • methods
  • Smooth of a ROC curve (sometimes the classification is based on a discrete scale (e.g. for a cancer diagnostic tool: "normal", "benign", "probably benign", "suspicious", "malignant") and smoothing methods fit a continuous curve based on the assumptions of the background distribution). (smart-statistics.com)
  • threshold
  • The ROC curve is created by plotting the true positive rate (TPR) against the false positive rate (FPR) at various threshold settings. (wikipedia.org)
  • diagnostic
  • The index is defined for all points of an ROC curve, and the maximum value of the index may be used as a criterion for selecting the optimum cut-off point when a diagnostic test gives a numeric rather than a dichotomous result. (wikipedia.org)
  • Figure
  • The resulting ROC curves from Resnik's and Robinson's measures give better results than those provided by PhenomeNET (Figure 6A). (nih.gov)
  • The ROC curve with CBG values as the screening variable and VPG values as the reference (positive actual state 7.0 mmol/L (126 mg/dl)) is shown in Figure 1 and the ROC curves with CBG and VPG as the screening variables and HbA1c as the reference (positive actual state 7%) are provided in Figure 2.
