A receiver operating characteristic curve, or ROC curve, is a graphical plot that illustrates the performance of a binary classifier model (can be used for multi class classification as well) at varying threshold values. The ROC curve is the plot of the true positive rate (TPR) against the false positive rate (FPR) at each threshold setting.
The relationship between sensitivity and specificity, as well as the performance of the classifier, can be visualized and studied using the Receiver Operating Characteristic (ROC) curve. In theory, sensitivity and specificity are independent in the sense that it is possible to achieve 100% in both (such as in the red/blue ball example given above).
An image of different ROC curves is shown in Figure 1. ROC curves provide a simple visual method for one to determine the boundary limit (or the separation threshold) of a biomarker or a combination of biomarkers for the optimal combination of sensitivity and specificity. The AUC (area under the curve) of the ROC curve reflects the overall ...
The company Reckitt/Mead Johnson Nutrition has voluntarily recalled certain types of Enfamil baby formula over fears of possible contamination, according to the Food and Drug Administration (FDA ...
While supply chain hiccups, labor shortages and other formula recalls have caused huge problems in the U.S. supply of baby formula over the last few years, most issues have been resolved, so the ...

An example of ROC curve and the area under the curve (AUC). The area under the ROC curve (AUC) [1] [2] is often used to summarize in a single number the diagnostic ability of the classifier. The AUC is simply defined as the area of the ROC space that lies below the ROC curve. However, in the ROC space there are regions where the values of FPR ...
Abbott Nutrition is expanding its recall of powdered baby food formulas to include some Similac PM 60/40 cans and cases produced at a Michigan facility.
