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.




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.
