La direction de provenance des rayons cosmiques, aux énergies les plus élevées, est facilement mesurable par les détecteurs modernes. Avec des statistiques suffisantes, l'interprétation de cette information devrait donner des indications fortes sur l'origine de ces rayons cosmiques. Toutefois, pour que de telles informations soient fiables, le choix des méthodes statistiques est extrêmement important. Nous résumons dans cet article les conclusions que l'on peut tirer à partir des données actuellement disponibles, et nous proposons les méthodes qui nous semblent nécessaires pour l'interprétation statistique des grandes quantités de données qui devraient devenir disponibles dans un futur proche.

The incident directions of cosmic ray particles at the highest energies are readily measured by modern detectors. Provided that there are sufficient data, the interpretation of such directions should give strong information on the origin of cosmic rays. However, the choice of statistical methods used in such an analysis can be of paramount importance in the reliability of the interpretation. This article summarizes the conclusions which may be drawn from the present data, and proposes methods needed to interpret statistically the large quantities of data which will become available in the near future.
