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…

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…
