cr is the frequency of correct rejections
or true negatives (
in a population of
An object of class
numeric of length 1.
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.
cr depends on the specificity
(aka. true negative rate, TNR)
and is conditional on the prevalence
to other frequencies:
In a population of size
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
