comp_fart: Compute a decision's false alarm rate from its specificity.

Description

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.

Usage

comp_fart(spec)

Arguments

spec

The decision's specificity value spec as a probability.

Value

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

Details

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.

Examples

# NOT RUN {
comp_fart(2)                       # => NA + warning (beyond range)
comp_fart(1/3)                     # => 0.6666667
comp_fart(comp_complement(0.123))  # => 0.123
