Missing data augmentation for Bayesian exponential random multi-graph models

RW Krause, A Caimo - Complex Networks X: Proceedings of the 10th …, 2019 - Springer
In this paper we present an estimation algorithm for Bayesian exponential random multi-
graphs (BERmGMs) under missing network data. Social actors are often connected with …

Bayesian exponential random graph models with nodal random effects

S Thiemichen, N Friel, A Caimo, G Kauermann - Social Networks, 2016 - Elsevier
We extend the well-known and widely used exponential random graph model (ERGM) by
including nodal random effects to compensate for heterogeneity in the nodes of a network …

Bayesian analysis for partially observed network data, missing ties, attributes and actors

JH Koskinen, GL Robins, P Wang, PE Pattison - Social networks, 2013 - Elsevier
We consider partially observed network data as defined in Handcock and Gile (2010). More
specifically we introduce an elaboration of the Bayesian data augmentation scheme of …

software which provides a comprehensive framework for Bayesian analysis for exponential …

Analysing exponential random graph (p-star) models with missing data using Bayesian data augmentation

JH Koskinen, GL Robins, PE Pattison - Statistical Methodology, 2010 - Elsevier
Missing data are often problematic in social network analysis since what is missing may
potentially alter the conclusions about what we have observed as tie-variables need to be …

Nonparametric estimation and testing of exchangeable graph models

J Yang, C Han, E Airoldi - Artificial Intelligence and Statistics, 2014 - proceedings.mlr.press
Exchangeable graph models (ExGM) are a nonparametric approach to modeling network
data that subsumes a number of popular models. The key object that defines an ExGM is …

Stochastic weighted graphs: Flexible model specification and simulation

JD Wilson, MJ Denny, S Bhamidi, SJ Cranmer… - Social Networks, 2017 - Elsevier
