Goodness of fit for stochastic actor-oriented models [PDF]
Methodological Innovations, 2019 We propose a Mahalanobis distance–based Monte Carlo goodness of fit testing procedure for the family of stochastic actor-oriented models for social network evolution.

Assessing and accounting for time heterogeneity in stochastic actor oriented models. [PDF]
Adv Data Anal Classif, 2011 This paper explores time heterogeneity in stochastic actor oriented models (SAOM) proposed by Snijders (Sociological Methodology. Blackwell, Boston, pp 361-395, 2001) which are meant to study the evolution of networks. SAOMs model social networks as directed graphs with nodes representing people, organizations, etc., and dichotomous relations ...

Analysing animal social network dynamics: the potential of stochastic actor-oriented models. [PDF]
J Anim Ecol, 2017 Summary Animals are embedded in dynamically changing networks of relationships with conspecifics. These dynamic networks are fundamental aspects of their environment, creating selection on behaviours and other traits. However, most social network‐based approaches in ecology are constrained to considering networks as static, despite several calls for

Accounting for edge uncertainty in stochastic actor-oriented models for dynamic network analysis. [PDF]
Netw Sci (Camb Univ Press)Abstract Stochastic Actor-Oriented Models (SAOMs) were designed in the social network setting to capture network dynamics representing a variety of influences on network change. The standard framework assumes the observed networks are free of false positive and false negative edges, which may be an unrealistic assumption.

Stochastic actor‐oriented modelling of the impact of COVID‐19 on financial network evolution [PDF]
Stat, 2021 The coronavirus disease 2019 (COVID‐19) pandemic has led to tremendous loss of human life and has severe social and economic impacts worldwide. The spread of the disease has also caused dramatic uncertainty in financial markets, especially in the early stages of the pandemic.

The dynamics of intergenerational closure and family networks of social cohesion
Frontiers in Sociology, 2023 We investigate the correlation of ties among school-children's parents with violence in schools, and two mechanisms of intergenerational closure (IC). Coleman described ties among parents of befriended children as IC.

Relative importance of effects in stochastic actor-oriented models [PDF]
Network Science, 2013 AbstractA measure of relative importance of network effects in the stochastic actor-oriented model (SAOM) is proposed. The SAOM is a parametric model for statistical inference in longitudinal social networks. The complexity of the model makes the interpretation of inferred results difficult. So far, the focus is on significance tests while the relative
