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

A theoretical and empirical comparison of the temporal exponential random graph model and the stochastic actor-oriented model [PDF]
Network Science, 2019 AbstractThe temporal exponential random graph model (TERGM) and the stochastic actor-oriented model (SAOM, e.g., SIENA) are popular models for longitudinal network analysis. We compare these models theoretically, via simulation, and through a real-data example in order to assess their relative strengths and weaknesses.

Envisaging the Unobserved: a Stochastic Actor-Oriented Model for Systems of Overlapping Subgroups
This paper presents a novel statistical framework for modeling cohesive subgroups in cross-sectional network data, adhering to prior ideas about the mean and variance of the number of actors per subgroup and subgroups per actor. Subgroups emerge from actors' membership decisions, with cohesion driven by their preference to co-member with network ...

Determinants of the Global Timber Trade Network Evolution a Stochastic Actor-Oriented Model Analysis
ForestsAgainst the backdrop of accelerating restructuring in the global economy and trade landscape, understanding the evolutionary mechanisms of timber trade networks has become increasingly crucial. Utilizing cross-national timber trade data from 2000 to 2024, this study applies a Stochastic Actor-Oriented Model to analyze the dynamic evolution of the ...

The Role of Cognitive Emotion Regulation for Making and Keeping Friend and Conflict Networks
Frontiers in Psychology, 2022 We used social network analysis (SNA) to examine how adaptive ER strategies (acceptance, positive reappraisal, refocusing, and putting in perspective) and maladaptive ER strategies (rumination, catastrophizing, self- and other-blame) predict the creation

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.
