A spatial Bayesian semiparametric mixture model for positive definite matrices with applications in diffusion tensor imaging
CANADIAN JOURNAL OF STATISTICS-REVUE CANADIENNE DE STATISTIQUE, 49(1), 129–149.
author keywords: Diffusion tensor imaging; inverse Wishart distribution; matrix variate; positive definite matrix; spatial statistics
TL;DR:
A matrix‐variate Bayesian semiparametric mixture model is proposed, where the p.d. matrices are distributed as a mixture of inverse Wishart distributions, with the spatial dependence captured by a Markov model for the mixture component labels.

Geostatistical modeling of positive-definite matrices: An application to diffusion tensor imaging
BIOMETRICS, 78(2), 548–559.
author keywords: Cholesky decomposition; diffusion tensor imaging; geostatistical modeling; positive‐ definite matrix; spatial random fields; spatial Wishart process
MeSH headings : Computer Simulation; Diffusion Tensor Imaging; Normal Distribution; Stochastic Processes
TL;DR:
An approximation method is proposed to obtain a feasible Cholesky decomposition model, which is shown to be asymptotically equivalent to the spatial Wishart process model and to produce reliable inference and improved performance, compared to other methods.
