| comp_spec {riskyr} | R Documentation |
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 |
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.
