Non-Euclidean Statistics Building on Generalized Fréchet Means

ABSTRACT:
Fréchet extended the concept of the expected value of a random variable in a Euclidean space to the minimizer of expected squared distance on a metric space. If the metric space is a manifold, the concept of covariance or principal compontents generalizes similarly, but slightly less canonically to best approximating geodesics, or best approximating subspaces subject to some restrictions. We introduce such generalized Fréchet means, investigate some of their surprising asymptotic properties and give applications.
