Abstract or Description

We generalize the Tukey depth to use cones instead of halfspaces. We prove a generalization of the center point theorem that for S ⊂ R2, there is a point s ∈S, with depth at least n/d+1 for cones of half-angle 45◦. This gives a notion of data depth for which an approximate median can always be found among the original set.
