Model-based Clustering for Network Data via a Latent Shrinkage Position Cluster Model

XY Gwee, IC Gormley, M Fop - arXiv preprint arXiv:2310.03630, 2023 - arxiv.org
Low-dimensional representation and clustering of network data are tasks of great interest
across various fields. Latent position models are routinely used for this purpose by assuming …

A latent shrinkage position model for binary and count network data

XY Gwee, IC Gormley, M Fop - Bayesian Analysis, 2023 - projecteuclid.org
Interactions between actors are frequently represented using a network. The latent position
model is widely used for analysing network data, whereby each actor is positioned in a …

Latent position network models

H Kaur, R Rastelli, N Friel, AE Raftery - arXiv preprint arXiv:2304.02979, 2023 - arxiv.org
In this chapter, we present a review of latent position models for networks. We review the
recent literature in this area and illustrate the basic aspects and properties of this modeling …

Asymptotically normal estimation of local latent network curvature

S Wilkins-Reeves, T McCormick - arXiv preprint arXiv:2211.11673, 2022 - arxiv.org
Network data, commonly used throughout the physical, social, and biological sciences,
consists of nodes (individuals) and the edges (interactions) between them. One way to …

Edge sampling using local network information

CM Le - Journal of Machine Learning Research, 2021 - jmlr.org
Edge sampling is an important topic in network analysis. It provides a natural way to reduce
network size while retaining desired features of the original network. Sampling methods that …

Model-based clustering for multidimensional social networks

S D'Angelo, M Alfò, M Fop - Journal of the Royal Statistical …, 2023 - academic.oup.com
Social network data are relational data recorded among a group of actors, interacting in
different contexts. Often, the same set of actors can be characterised by multiple social …

Latent Space Network Modelling with Hyperbolic and Spherical Geometries

M Papamichalis, K Turnbull, S Lunagomez… - arXiv preprint arXiv …, 2021 - arxiv.org
A rich class of network models associate each node with a low-dimensional latent
coordinate that controls the propensity for connections to form. Models of this type are well …

Gravity with Strategic Behavior

B Eke Rubini, L Rubini - Available at SSRN 4976538, 2024 - papers.ssrn.com
The assumptions underlying the estimation of Gravity equations imply that a country's
behavior is independent of the actions of others. In practice, a few countries heavily …

Advances in Bayesian modelling of array structured data

F Pavone - 2024 - iris.unibocconi.it
Data organized in array structures arise in various domains. Each entry of the array serves
as a statistical unit, while the dimensions correspond to indexing attributes. The inherent …

Statistical Inference with Missing and Latent Data: Methods for Data Harmonization, Network Curvature Estimation and Experimentation Under Interference

S Wilkins-Reeves - 2024 - search.proquest.com
This dissertation explores several statistical challenges involving inference problems where
the object of interest is a latent phenomenon or involves missing data. Effective modeling of …
