Two-Sample Hypothesis Testing for Subspace Equality in Network Data
Rajdeep Brahma, Joshua Agterberg, Yuguo Chen
In many settings one is often interested in determining whether two networks share some joint structural connectivity patterns such as communities. However, while communities may b…
Semiparametric analysis for paired comparisons with covariates
Haoyue Song, Lianqiang Qu, Ting Yan +1
Statistical inference in parametric models (e.g., the Bradley--Terry model and its variants) for paired-comparison data has been explored in the high-dimensional regime, in which t…
Network Cross-Validation and Model Selection via Subsampling
Sayan Chakrabarty, Srijan Sengupta, Yuguo Chen
Complex and larger networks are becoming increasingly prevalent in scientific applications in various domains. Although a number of models and methods exist for such networks, cros…
Temporal network analysis via a degree-corrected Cox model
Yuguo Chen, Lianqiang Qu, Jinfeng Xu +2
Temporal dynamics, characterised by time-varying degree heterogeneity and homophily effects, are often exhibited in many real-world networks. As observed in an MIT Social Evolution…
Inference in semiparametric formation models for directed networks
Lianqiang Qu, Lu Chen, Ting Yan +1
We propose a semiparametric model for dyadic link formations in directed networks. The model contains a set of degree parameters that measure different effects of popularity or out…
