Asymptotics for multivariate trimming

Abstract

One version of multivariate trimming is the operation that intersects all halfspaces with probability content 1-[alpha] or greater. The result is a [alpha]-trimmed convex set, and this set is stochastic when the empirical distribution of a sample determines the probability content of the halfspaces. In this paper, conditions are found for the weak convergence of the boundary of this set to a Gaussian process. It is also shown that an n1/3 normalization produces a limit distribution for the direction normal to the boundary of the set. Intuitive geometric arguments and empirical process methods are employed to establish both limit results.
