`dec_err`

is a frequency that describes the
number of individuals in the current population `N`

for which the decision is incorrect or erroneous (i.e., cases in which the
decision does not correspond to the condition).

`dec_err`

An object of class `numeric`

of length 1.

Key relationships:

to probabilities: The frequency of

`dec_err`

individuals depends on the population size`N`

and is equal to the sum of false negatives`mi`

and false positives`fa`

.to other frequencies: In a population of size

`N`

the following relationships hold:

Current frequency information is computed by
`comp_freq`

and contained in a list
`freq`

.

Consult Wikipedia: Confusion matrix for additional information.

`is_freq`

`num`

contains basic numeric parameters;
`init_num`

`freq`

contains current frequency information;
`comp_freq`

computes current frequency information;
`prob`

contains current probability information;
`comp_prob`
