Non-Euclidean statistical analysis of covariance matrices and diffusion tensors
Ian L. Dryden, Alexey Kolydenko, Diwei Zhou +1
The statistical analysis of covariance matrices occurs in many important applications, e.g. in diffusion tensor imaging and longitudinal data analysis. We consider the situation wh…

Bayesian matching of unlabelled point sets using Procrustes and configuration models
Kim Kenobi, Ian L. Dryden
The problem of matching unlabelled point sets using Bayesian inference is considered. Two recently proposed models for the likelihood are compared, based on the Procrustes size-and…

Power Euclidean metrics for covariance matrices with application to diffusion tensor imaging
Ian L. Dryden, Xavier Pennec, Jean-Marc Peyrat
Various metrics for comparing diffusion tensors have been recently proposed in the literature. We consider a broad family of metrics which is indexed by a single power parameter. A…
