dec_neg is a frequency that describes the
number of individuals in the current population
for which the decision is negative (i.e., cases not called or not predicted).
An object of class
numeric of length 1.
The frequency of
dec_neg individuals depends on the population size
the decision's proportion of negative decisions
(1 - ppod) and is split further into two subsets of
cr by the negative predictive value
mi by the false omission rate
FOR = 1 - NPV.
to other frequencies:
In a population of size
N the following relationships hold:
