The area under the receiver operating characteristic (ROC) curve is another diagnostic accuracy measurement, complementary to the sensitivity and specificity [...
of units for expressing the amounts of various quantities such as length, mass, time, and temperature. As of 1994, every nation in the world has adopted the metric system, with only four exceptions: the United States, Brunei, Burma, and Yemen (which use the English units of measurement)....
The metric system of measurement is so much easier to use than the British Imperial system — which is somehow still in use in the United States in 2018 — that every country in the world except three has adopted it. Even the United Kingdom has made the change. Instead of the 12 gradat...
