CRT*: Conditional Randomization Testing with Heterogeneous External and Unlabeled Data
Yingjie Zhang, Ziqi Chen, Chenlei Leng
The conditional randomization test (CRT) provides a principled approach to conditional independence (CI) testing, guaranteeing exact type-I error control when the true conditional…
Supervised centrality via sparse network influence regression: an application to the 2021 Henan floods' social network
Yingying Ma, Wei Lan, Chenlei Leng +2
The social characteristics of players in a social network are closely associated with their network positions and relational importance. Identifying those influential players in a…
A two-way heterogeneity model for dynamic networks
Binyan Jiang, Chenlei Leng, Ting Yan +2
Dynamic network data analysis requires joint modelling individual snapshots and time dynamics. This paper proposes a new two-way heterogeneity model towards this goal. The new mode…
Optimal Subsampling Bootstrap for Massive Data
Yingying Ma, Chenlei Leng, Hansheng Wang
The bootstrap is a widely used procedure for statistical inference because of its simplicity and attractive statistical properties. However, the vanilla version of bootstrap is no…
Testing the Graph of a Gaussian Graphical Model
Thien-Minh Le, Ping-Shou Zhong, Chenlei Leng
The Gaussian graphical model is routinely employed to model the joint distribution of multiple random variables. The graph it induces is not only useful for describing the relation…
Linear Discriminant Analysis with High-dimensional Mixed Variables
Binyan Jiang, Chenlei Leng, Cheng Wang +2
Datasets containing both categorical and continuous variables are frequently encountered in many areas, and with the rapid development of modern measurement technologies, the dimen…
