comp_spec is a conversion function that takes a false alarm rate fart -- given as a probability (i.e., a numeric value in the range from 0 to 1) -- as its input, and returns the corresponding specificity spec -- also as a probability -- as its output.

comp_spec(fart)

Arguments

fart

The decision's false alarm rate fart as a probability.

Value

The decision's specificity spec as a probability.

Details

The specificity spec and the false alarm rate fart are complements (spec = (1 - fart)) and both features of the decision process (e.g., a diagnostic test).

The function comp_spec is complementary to the conversion function comp_fart 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.
