mi {riskyr} | R Documentation |
Frequency of misses or false negatives (FN).
Description
mi
is the frequency of misses
or false negatives (FN
)
in a population of N
individuals.
Usage
mi
Format
An object of class numeric
of length 1.
Details
Definition:
mi
is the frequency of individuals for which
Condition = TRUE
and Decision = FALSE
(negative).
mi
is a measure of incorrect classifications
(type-II errors), not an individual case.
Relationships:
to probabilities: The frequency
mi
depends on the miss ratemirt
(aka. false negative rate, FNR) and is conditional on the prevalenceprev
.to other frequencies: In a population of size
N
the following relationships hold:
