Large sample theory of intrinsic and extrinsic sample means on manifolds—II
TL;DR: In this article, a central limit theorem for Frechet sample means is derived leading to an asymptotic distribution theory of intrinsic sample means on Riemannian manifolds.

Journal ArticleDOI
Directions and projective shapes
Kanti V. Mardia,Vic Patrangenaru +1 more
TL;DR: In this paper, the Frechet extrinsic mean for the multivariate axial case is derived for both parametric and nonparametric tests, as well as asymptotic distributions of the appropriate parametric tests are derived.
Journal ArticleDOI
Sticky central limit theorems on open books
Thomas Hotz,Sean Skwerer,Stephan Huckemann,Huiling Le,James Stephen Marron,Jonathan C. Mattingly,Ezra Miller,James Nolen,Megan Owen,Vic Patrangenaru +9 more
TL;DR: In this article, the authors define a precise concept of when the Fr\'{e}chet mean (barycenter) is sticky and show that the empirical mean eventually almost surely lies on the spine that is the glued hyperplane.
Journal ArticleDOI
Nonparametic estimation of location and dispersion on Riemannian manifolds
TL;DR: A central limit theorem for intrinsic mean on a complete flat manifold and some asymptotic properties of the intrinsic total sample variance on an arbitrary complete manifold are given in this paper.
