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).

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:
N = cond.true + cond.false
(by condition)
N = dec.pos + dec.neg
(by decision)
N = dec.cor + dec.err
(by correspondence of decision to condition)
dec.cor = hi + cr
dec.err = mi + fa
N = hi + mi + fa + cr
(by condition x decision)
