Marginal Coordinate Test for Fréchet Regression with Random Objects
Jiaye Chen, Rui Qiu, Roulin Wang +1
We develop a marginal coordinate test for regression with Euclidean predictors and a random-object response in a separable metric space. The goal is to test whether a predictor pro…

Semi-supervised Fréchet Regression
Rui Qiu, Zhou Yu, Zhenhua Lin
This paper explores the field of semi-supervised Fréchet regression, driven by the significant costs associated with obtaining non-Euclidean labels. Methodologically, we propose tw…

Sparse Fréchet Sufficient Dimension Reduction with Graphical Structure Among Predictors
Jiaying Weng, Kai Tan, Cheng Wang +1
Fréchet regression has received considerable attention to model metric-space valued responses that are complex and non-Euclidean data, such as probability distributions and vectors…
