Its successĬan be attributed to the increasing worldwide demand for professional statistical The oldest scientific associations operating in the modern world. La discussion se fonde surtout sur le cas où les observations proviennent du cercle ou de la sphère, mais une section sur les espaces d'échantillonage non-sphériques est incluse.Įstablished in 1885, the International Statistical Institute (ISI) is one of On considère des méthodes paramétriques, non-paramétriques et informelles.

De plus on identifie trois points de vue fondamentaux de la statistique directionelle, dans lesquels l'espace d'échantillonage de base, la sphère, est considéré respectivement comme étant un sous-ensemble de l'espace euclidien, un objet en lui-même et une entité approximée par une surface tangente. L'attention est portée sur les rapports entre la théorie sous-jacente et quelques idées clefs: familles exponentielles, modèles de transformation, décompositions tangentes-normales, transformations en problèmes multidimensionnels, et le théorème limite centrale. Cet article présente une approche cohérente de ces dévelopments. / De nombreux articles sur la théorie et la pratique de la statistique directionnelle ont paru depuis la revue du sujet par Mardia (1975a).
The discussion is mainly of observations on the circle or sphere but a section on non-spherical sample spaces is included. Parametric, nonparametric and informal methods are considered.
Further unification is attained by identifying three basic approaches to directional statistics, in which the basic sample space, the sphere, is regarded respectively as a subset of Euclidean space, an object in its own right and as something approximated by a tangent plane. This paper aims to present a coherent view of the theory of the topic by relating these developments to the following key ideas: exponential families, transformation models, 'tangent-normal' decompositions, transformations to multivariate problems and the central limit theorem. Numerous articles on the theory and practice of directional statistics have appeared since Mardia's (1975a) survey.
