An Outlyingness Matrix for Multivariate Functional Data Classification

Wenlin Dai, Marc G. Genton

The classification of multivariate functional data is an important task in scientific research. Unlike point-wise data, functional data are usually classified by their shapes rathe…

Directional Outlyingness for Multivariate Functional Data

Wenlin Dai, Marc G. Genton

The direction of outlyingness is crucial to describing the centrality of multivariate functional data. Motivated by this idea, we generalize classical depth to directional outlying…
