Stochastic Actor-Oriented Models for Network Dynamics [PDF]

open access: yesAnnual Review of Statistics and Its Application, 2017
Stochastic Actor Oriented Models for Network Dynamics are used for the statistical analysis of longitudinal network data collected as a panel. The probability model defines an unobserved stochastic process of tie changes, where social actors add new ties or drop existing ties in response to the current network structure; the panel observations are ...

Choice modelling in social networks using stochastic actor-oriented models [PDF]

open access: yesJournal of Choice Modelling, 2020
Abstract Combining choice modelling with social network analysis, we show how the stochastic actor-oriented model for the co-evolution of networks and behavior (SAOM) can be used as a powerful statistical framework to empirically analyze network-related choices.

Stochastic actor oriented model with random effects

open access: yesSocial Networks
The stochastic actor oriented model (SAOM) is a method for modelling social interactions and social behaviour over time. It can be used to model drivers of dynamic interactions using both exogenous covariates and endogenous network configurations, but also the co-evolution of behaviour and social interactions.

Visualization methods for longitudinal social networks and stochastic actor-oriented modeling [PDF]

open access: yesSocial Networks, 2012
Abstract As a consequence of the rising interest in longitudinal social networks and their analysis, there is also an increasing demand for tools to visualize them. We argue that similar adaptations of state-of-the-art graph-drawing methods can be used to visualize both, longitudinal networks and predictions of stochastic actor-oriented models (SAOMs),

Contemporaneous Statistics for Estimation in Stochastic Actor-Oriented Co-evolution Models [PDF]

open access: yesPsychometrika, 2019
Stochastic actor-oriented models (SAOMs) can be used to analyse dynamic network data, collected by observing a network and a behaviour in a panel design. The parameters of SAOMs are usually estimated by the method of moments (MoM) implemented by a stochastic approximation algorithm, where statistics defining the moment conditions correspond in a ...

Assessing and accounting for time heterogeneity in stochastic actor oriented models [PDF]

open access: yesAdvances in Data Analysis and Classification, 2010
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 ...
