Asymptotic Normality of the Hill Estimator in Linear Preferential Attachment
Tiandong Wang
We prove asymptotic normality of the Hill estimator based on the largest degrees in a homogeneous linear preferential attachment graph with vertices. Each new vertex send…
Pooling Mobility Obscures Epidemic Invasion Routes
Tiandong Wang, Wei Yang
Epidemic models often pool air travel, commuting, and other mobility layers into a single weighted network. Pooling keeps the total imported infections into a region but discards t…
Hub Neighbor-Degree Diagnostics for Sparse Random Graphs
Qian Hui, Tiandong Wang
Networks with nearly identical degree distributions can place their hubs in sharply different neighborhoods. We develop a model diagnostic based on the mean degree of the neighbors…
Efficient Topic Model Estimation under Heavy-Tailed Document Lengths
Daniel Cirkovic, Tiandong Wang
Early inquiries into the statistical properties of natural language found that words tend to occur with power-law frequencies. This observation, closely associated with Zipf's law,…
Spatial Dependence in Directed Preferential-Attachment Networks
Zihan Li, Tiandong Wang
Spatially embedded directed networks, such as airline networks, often exhibit simultaneous high activity at nearby nodes. Preferential attachment (PA) explains hub dominance. We ex…
A Multilayer Probit Network Model for Community Detection with Dependent Edges and Layers
Dapeng Shi, Haoran Zhang, Tiandong Wang +1
Community detection in multilayer networks, which aims to identify groups of nodes exhibiting similar connectivity patterns across multiple network layers, has attracted considerab…
