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

In hneth/riskyr: Rendering Risk Literacy more Transparent

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

Description

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.

Usage

comp_spec(fart)

Arguments

fart	The decision's false alarm rate fart 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.

Value

The decision's specificity spec as a probability.

See Also

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

comp_spec(2)                       # => NA + warning (beyond range)
comp_spec(1/3)                     # => 0.6666667
comp_spec(comp_complement(0.123))  # => 0.123
