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…
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…
Maximum likelihood estimation in the sparse Rasch model
Pai Peng, Lianqiang Qu, Qiuping Wang +2
The Rasch model has been widely used to analyse item response data in psychometrics and educational assessments. When the number of individuals and items are large, it may be impra…
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…
