Additive Models for Symmetric Positive-Definite Matrices, Riemannian Manifolds and Lie groups

Zhenhua Lin, Hans-Georg Müller, Byeong U. Park

In this paper an additive regression model for a symmetric positive-definite matrix valued response and multiple scalar predictors is proposed. The model exploits the abelian group…

Intrinsic Riemannian Functional Data Analysis for Sparse Longitudinal Observations

Lingxuan Shao, Zhenhua Lin, Fang Yao

A new framework is developed to intrinsically analyze sparsely observed Riemannian functional data. It features four innovative components: a frame-independent covariance function,…

High-dimensional MANOVA via Bootstrapping and its Application to Functional and Sparse Count Data

Zhenhua Lin, Miles E. Lopes, Hans-Georg Müller

We propose a new approach to the problem of high-dimensional multivariate ANOVA via bootstrapping max statistics that involve the differences of sample mean vectors. The proposed m…

Mean and Covariance Estimation for Functional Snippets

Zhenhua Lin, Jane-Ling Wang

We consider estimation of mean and covariance functions of functional snippets, which are short segments of functions possibly observed irregularly on an individual specific subint…

Wasserstein Regression

Yaqing Chen, Zhenhua Lin, Hans-Georg Müller

The analysis of samples of random objects that do not lie in a vector space is gaining increasing attention in statistics. An important class of such object data is univariate prob…
