Topics
R (langage) Confidence: 87% Arrow up

R est un langage informatique dédié aux statistiques et à la science des données.

Analyse des données Confidence: 84% Arrow up

L’analyse des données est une famille de méthodes statistiques dont les principales caractéristiques sont d'être multidimensionnelles et descriptives.

Certaines méthodes, pour la plupart géométriques, aident à faire ressortir les relations pouvant exister entre les différentes données et à en tirer une information statistique qui permet de décrire de façon plus succincte les principales informations contenues dans ces données.

D'autres techniques permettent de regrouper les données de façon à faire apparaître clairement ce qui les rend homogènes, et ainsi mieux les connaître.

Donnée (informatique) Confidence: 77% Arrow up

Dans les technologies de l'information, une donnée (data en anglais) est la représentation d'une information dans un programme: soit dans le texte du programme (code source), soit en mémoire durant l'exécution.

Les données, souvent codées, décrivent les éléments du logiciel tels qu'une entité (chose), une interaction, une transaction, un événement, un sous-système.
