Quantile Social Autoregressive Model
Liyuan Wang, Danyang Huang, Wei Lan +1
Research on modelling peer effects has predominantly relied on linear-in-means models. However, averaging peer responses prevents these models from capturing the effects of extreme…
Maximum-of-Differences Test for Comparing Multivariate K-Sample Distributions
Wei Lan, Long Feng, Runze Li +1
Comparing -sample distributions is a fundamental problem in data science that arises in a wide variety of fields and applications. In this article, we introduce a maximum-of-dif…
A spectral inference method for determining the number of communities in networks
Yujia Wu, Xiucai Ding, Jingfei Zhang +2
To characterize the community structure in network data, researchers have developed various block-type models, including the stochastic block model, the degree-corrected stochastic…
A Goodness-of-Fit Test for Sparse Networks
Yujia Wu, Wei Lan, Long Feng +1
The stochastic block model (SBM) has been widely used to analyze network data. Various goodness-of-fit tests have been proposed to assess the adequacy of model structures. To the b…
An Eigengap Ratio Test for Determining the Number of Communities in Network Data
Yujia Wu, Jingfei Zhang, Wei Lan +1
To characterize the community structure in network data, researchers have introduced various block-type models, including the stochastic block model, degree-corrected stochastic bl…
