# comp_FOR

##### Compute a decision's false omission rate (FOR) from probabilities.

`comp_FOR`

computes the false omission rate `FOR`

from 3 essential probabilities
`prev`

, `sens`

, and `spec`

.

##### Usage

`comp_FOR(prev, sens, spec)`

##### Arguments

- prev
The condition's prevalence

`prev`

(i.e., the probability of condition being`TRUE`

).- sens
The decision's sensitivity

`sens`

(i.e., the conditional probability of a positive decision provided that the condition is`TRUE`

).- spec
The decision's specificity value

`spec`

(i.e., the conditional probability of a negative decision provided that the condition is`FALSE`

).

##### Details

`comp_FOR`

uses probabilities (not frequencies)
and does not round results.

##### Value

The false omission rate `FOR`

as a probability.
A warning is provided for NaN values.

```
# NOT RUN {
# (1) Ways to work:
comp_FOR(.50, .500, .500) # => FOR = 0.5 = (1 - NPV)
comp_FOR(.50, .333, .666) # => FOR = 0.5004 = (1 - NPV)
# }
```
