Understanding or obtaining the miss rate `mirt`

:

Definition:

`sens`

is the conditional probability for an incorrect negative decision given that the condition is`TRUE`

:`mirt = p(decision = negative | condition = TRUE)`

or the probability of failing to detect true cases (

`condition = TRUE`

).Perspective:

`mirt`

further classifies the subset of`cond.true`

individuals by decision (`mirt = mi/cond.true`

).Alternative names: false negative rate (

`FNR`

), rate of type-II errors (`beta`

)Relationships:

a.

`mirt`

is the complement of the sensitivity`sens`

(aka. hit rate`HR`

):`mirt = (1 - sens) = (1 - HR)`

b.

`mirt`

is the _opposite_ conditional probability – but not the complement – of the false omission rate`FOR`

:`FOR = p(condition = TRUE | decision = negative)`

In terms of frequencies,

`mirt`

is the ratio of`mi`

divided by`cond.true`

(i.e.,`hi + mi`

):`mirt = mi/cond.true = mi/(hi + mi)`

Dependencies:

`mirt`

is a feature of a decision process or diagnostic procedure and a measure of incorrect decisions (false negatives).However, due to being a conditional probability, the value of

`mirt`

is not intrinsic to the decision process, but also depends on the condition's prevalence value`prev`

.

Consult Wikipedia for additional information.
