Nonparametric two-sample tests on homogeneous Riemannian manifolds, Cholesky decompositions and Diffusion Tensor Image analysis

Osborne, Daniel; Patrangenaru, Vic; Ellingson, Leif; … - In: Journal of Multivariate Analysis 119 (2013) C, pp. 163-175

This paper addresses much needed asymptotic and nonparametric bootstrap methodology for two-sample tests for means on Riemannian manifolds with a simply transitive group of isometries. In particular, we develop a two-sample procedure for testing the equality of the generalized Frobenius means of...
