cond_false is a frequency that describes the
number of individuals in the current population
for which the condition is
FALSE (i.e., actually false cases).
An object of class
numeric of length 1.
The frequency of
cond_false individuals depends on the population size
the complement of the condition's prevalence
1 - prev and is split further into two subsets of
fa by the false alarm rate
cr by the specificity
to other frequencies:
In a population of size
N the following relationships hold:
