Connecting pairwise spheres by depth: DCOPS. (arXiv:1710.02561v1 [math.ST])
来源于:arXiv
We introduce a new notion of depth of low computational complexity for high
dimensional data. For small dimensions, it behaves similarly to simplicial and
half-space depths. We show that this new depth notion shares the set of
desirable properties that were introduced in Serfling (1980). For the empirical
version of this depth function both uniform consistency and the asymptotic
distribution are studied. Our new notion is extended to the important setup of
data in Riemannian manifolds. The behaviour of the depth is illustrated through
several examples. 查看全文>>
