First developed by Donaldson [1]. See, Warm, Dember, and Howe, [2] compared several nonparmetric measures of response bias and endorse this measure when the assumption of a gaussian noise distribution does not hold.

classmethod direct(*args)¶

Calculates metric based on hit, miss, correct rejection, and false alarm counts

static prob(*args)¶

Calculates metric based on hit rate and false alarm rate

classmethod __call__(*args)¶

based on the number of args and the availability of .prob routes call to appropriate method.
