cr
is the frequency of correct rejections
or true negatives (TN
)
in a population of N
individuals.

An object of class numeric
of length 1.
Definition:
cr
is the frequency of individuals for which
Condition = FALSE
and Decision = FALSE
(negative).
cr
is a measure of correct classifications,
not an individual case.
Relationships:
to probabilities:
The frequency cr
depends on the specificity spec
(aka. true negative rate, TNR)
and is conditional on the prevalence prev
.
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)
N = hi + mi + fa + cr
(by condition x decision)
spec
is the specificity or correct rejection rate
(aka. true negative rate TNR
);
