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…
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…
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…
