- Hit rate [p("yes"|signal)] against false-alarm rate [p("yes"|noise)]
- when (1) the payoffs for hits, correct rejections, misses, and false
- alarms are varied, or (2) the prior probabilities of signal and noise
- are manipulated. In psychophysics we are trying to standardize the terminology
- to "isosensitivity function."
