A principal subspace theorem for 2-principal points of general location mixtures of spherically symmetric distributions
In this paper, we study 2-principal points of general location mixtures, including finite and infinite mixtures, of spherically symmetric distributions. A theorem is established that clarifies a linear subspace in which any set of 2-principal points exists.
