comp_fart is a conversion function that takes a specificity spec
-- given as a probability (i.e., a numeric value in the range from 0 to 1) --
as its input, and returns the corresponding false alarm rate fart
-- also as a probability -- as its output.
comp_fart(spec)The decision's specificity value spec as a probability.
The decision's false alarm rate fart as a probability.
The false alarm rate fart and specificity spec
are complements (fart = (1 - spec)) and both features of
the decision process (e.g., a diagnostic test).
The function comp_fart is complementary to the conversion function
comp_spec and uses the generic function
comp_complement.
comp_complement computes a probability's complement;
is_complement verifies probability complements;
comp_prob computes current probability information;
prob contains current probability information;
is_prob verifies probabilities.
