dec_err
is a frequency that describes the
number of individuals in the current population N
for which the decision is incorrect or erroneous (i.e., cases in which the
decision does not correspond to the condition).
dec_err
An object of class numeric
of length 1.
Key relationships:
to probabilities:
The frequency of dec_err
individuals depends on the population size N
and
is equal to the sum of false negatives mi
and false positives fa
.
to other frequencies:
In a population of size N
the following relationships hold:
Current frequency information is computed by
comp_freq
and contained in a list

.
