Kriging prediction for manifold-valued random fields
Pigoli, Davide; Menafoglio, Alessandra; Secchi, Piercesare (ElsevierJournal of Multivariate Analysis, 2015-12-25)The statistical analysis of data belonging to Riemannian manifolds is becoming increasingly important in many applications, such as shape analysis, diffusion tensor imaging and the analysis of covariance matrices. In many ...

Tests for separability in nonparametric covariance operators of random surfaces
Aston, John Alexander; Pigoli, Davide; Tavakoli, Shahin (Institute of Mathematical StatisticsAnnals of Statistics, 2016)The assumption of separability of the covariance operator for a random image or hypersurface can be of substantial use in applications, especially in situations where the accurate estimation of the full covariance structure ...
