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."
