`dec_cor`

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

for which the decision is correct/accurate
(i.e., cases in which the decision corresponds to the condition).

`dec_cor`

An object of class `numeric`

of length 1.

Key relationships:

to probabilities: The frequency of

`dec_cor`

individuals depends on the population size`N`

and the accuracy`acc`

.to other frequencies: In a population of size

`N`

the following relationships hold:correspondence: When not rounding the frequencies of

`freq`

then`dec_cor = N x acc = hi + cr`

(i.e.,

`dec_cor`

corresponds to the sum of true positives`hi`

and true negatives`cr`

.

Current frequency information is computed by
`comp_freq`

and contained in a list
`freq`

.

Consult Wikipedia: Confusion matrix for additional information.
