`N`

is a frequency that describes the
number of individuals in the current population
(i.e., the overall number of cases considered).

`N`

An object of class `numeric`

of length 1.

Key relationships between frequencies and probabilities
(see documentation of `comp_freq`

or `comp_prob`

for details):

Three perspectives on a population:

by condition / by decision / by accuracy.

Defining probabilities in terms of frequencies:

Probabilities can be computed as ratios between frequencies, but beware of rounding issues.

Current frequency information is computed by
`comp_freq`

and contained in a list
`freq`

.

Consult Wikipedia: Statistical population for additional information.

`is_freq`

verifies frequencies;
`num`

contains basic numeric parameters;
`init_num`

initializes basic numeric parameters;
`freq`

contains current frequency information;
`comp_freq`

computes current frequency information;
`prob`

contains current probability information;
`comp_prob`

computes current probability information.
