Conical Extremes of a Multivariate Sample

J Res Natl Inst Stand Technol. 1994 Jul-Aug;99(4):511-519. doi: 10.6028/jres.099.049.

Abstract

We introduce multivariate extremes in the direction of a given cone. Convergence results for the number of the kth extremes are obtained for sampling from a distribution having asymptotically independent radial and spherical components and regularly varying tail of the radial component.

Keywords: conical extremes; multivariate extremes; regular variation.
