Receiver operating characteristic (ROC) curves are used for summarizing the performance of imperfect diagnostic systems, especially in biomedical research. These curves are also appropriate for ...
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 ...
(A) ROC of the training set. (B) ROC of the validation set. (C) PR curve of the training set. (D) PR curve of the validation set. (E) Calibration curve of the training set. (F) Calibration curve of ...
This paper suggests a low cost methodology for identifying and assessing the accuracy of poverty monitoring and targeting indicators. It proposes that the non-parametric technique of Receiver ...
In a sample of n individuals, suppose n 1 individuals are observed to have a certain condition or event. Let this group be denoted by C 1, and let the group of the remaining n 2 =n-n 1 individuals who ...
The ROC curve is plotted by the GPLOT procedure, and the plot is shown in Output 39.6.3. symbol1 i=join v=none c=blue; proc gplot data=roc1; title 'ROC Curve'; plot _sensit_*_1mspec_=1 / vaxis=0 to 1 ...
The receiver operating characteristic (ROC) curve is often used by creditors to assess credit scoring accuracy and as part of their Basel II model validation. The purpose of this paper is to provide a ...
