Threshold stochastic unit root models [PDF]

, 2002
This paper introduces a new class of stochastic unit root (STUR) processes, where the randomness of the autorregresive unit root is driven by a threshold variable.

Structural Characteristics and Evolutionary Drivers of Global Virtual Water Trade Networks: A Stochastic Actor-Oriented Model for 2000-2015

SSRN Electronic Journal, 2022
The globalization of trade has caused tremendous pressure on water resources globally, and a virtual water trade provides a new perspective on global freshwater sharing and water sustainability. No study has yet explored the structural characteristics and drivers of the evolution of global virtual water trade networks from a network structure evolution

The Dynamics of Adolescents’ Pubertal Maturation, Depressive Symptoms and Friendship Networks: Stochastic Actor-Oriented Model

SSRN Electronic Journal, 2020
Abstract This study aimed to examine whether adolescents select friends based on their friends’ levels of depressive symptoms, and to determine whether the potential homophily phenomenon for depressive symptoms is attenuated after considering pubertal maturation and gender.

Introduction to stochastic actor-based models for network dynamics [PDF]

, 2010
Stochastic actor-based models are models for network dynamics that can represent a wide variety of influences on network change, and allow to estimate parameters expressing such influences, and test corresponding hypotheses.
