Using the Speed-Accuracy Operating Characteristic to Visualize Performance with Pointing Devices
There is a nearly limitless variety of alternatives to the traditional computer mouse, including trackballs, trackpads, joysticks, head-mounted mouse emulators, and eye-gaze systems, each with its own unique strengths and limitations. Two key challenges in selecting the most appropriate pointing device are (1) collecting accurate, comparable data describing the client's performance with each de...
متن کاملReceiver operating characteristic analysis of eyewitness memory: comparing the diagnostic accuracy of simultaneous versus sequential lineups.
A police lineup presents a real-world signal-detection problem because there are two possible states of the world (the suspect is either innocent or guilty), some degree of information about the true state of the world is available (the eyewitness has some degree of memory for the perpetrator), and a decision is made (identifying the suspect or not). A similar state of affairs applies to diagno...
متن کاملReceiver operating characteristic - Wikipedia, the free encyclopedia
In statistics, a receiver operating characteristic (ROC), or ROC curve, is a graphical plot that illustrates the performance of a binary classifier system as its discrimination threshold is varied. The curve is created by plotting the true positive rate against the false positive rate at various threshold settings. (The true-positive rate is also known as sensitivity in biomedical informatics, ...
متن کاملReceiver Operating Characteristic ( ROC ) Curves
Assessment of predictive accuracy is a critical aspect of evaluating and comparing models, algorithms or technologies that produce the predictions. In the field of medical diagnosis, receiver operating characteristic (ROC) curves have become the standard tool for this purpose and its use is becoming increasingly common in other fields such as finance, atmospheric science and machine learning. T...
متن کاملMeasuring diagnostic and predictive accuracy in disease management: an introduction to receiver operating characteristic (ROC) analysis.
Diagnostic or predictive accuracy concerns are common in all phases of a disease management (DM) programme, and ultimately play an influential role in the assessment of programme effectiveness. Areas, such as the identification of diseased patients, predictive modelling of future health status and costs and risk stratification, are just a few of the domains in which assessment of accuracy is be...
