D_{a}

Definition

$D_{a} = \log_{a} n$

where $a$ is the number of possibilities at each decision and $n$ the number of events

$D_{a} = \log_{a} n$

où $a$ est le nombre de possibilités à chaque décision et $n$ est le nombre d'événements

Notes

For the unit one, see the intro.

When the same base is used for the same number of events then $D_{a} = H_{0}$ where $H_{0}$ is maximum entropy (t13-26,item 13-26).

See IEC 60050-171,droploc%locality:item="171-07-10".

Pour l'unité un, voir l'intro.

Lorsque la même base est utilisée pour le même nombre d'événements, $D_{a} = H_{0}$ où $H_{0}$ est l'entropie maximale (t13-26,13-26).

Voir l'IEC 60050-171,droploc%locality:item="171-07-10".
