Meaning of ROC. {\displaystyle f_{0}} {\displaystyle {\mathcal {D}}^{1}} The military also faces difficulties in the recruitment and retention of junior officers and NCOs due to competition with the private sector. When the C method predicts p or n, the C′ method would predict n or p, respectively. [37], In 2020, Taiwan donated two UH-1H utility helicopters to Eswatini. denotes an indicator function which returns 1 iff ) [48] In the social sciences, ROC analysis is often called the ROC Accuracy Ratio, a common technique for judging the accuracy of default probability models. In 2001 the United States approved the sale of a number of weapons systems, including eight diesel submarines, six Patriot PAC-3 SAMs and 12 P-3C Orion maritime patrol aircraft. t The development of nuclear weapons by the ROC has been a contentious issue.

The total value of the 12 P-3C Orions were estimated at around$1.96 billion and \$272 million for the 144 SM-2 missiles. The best possible prediction method would yield a point in the upper left corner or coordinate (0,1) of the ROC space, representing 100% sensitivity (no false negatives) and 100% specificity (no false positives). f x [56] In the latter, RROC curves become extremely similar to ROC curves for classification, with the notions of asymmetry, dominance and convex hull. T The false-positive rate is also known as probability of false alarm[7] and can be calculated as (1 − specificity). For the same reason, more emphasis is being placed on the development of the Navy and Air Force, in order to fend off attacks in the Taiwan Strait, away from Taiwan proper. {\displaystyle X} ROC analysis since then has been used in medicine, radiology, biometrics, forecasting of natural hazards,[8] meteorology,[9] model performance assessment,[10] and other areas for many decades and is increasingly used in machine learning and data mining research.
