WORKSHOP: Goldfish: Estimating Network Event Models

17th May, 09:00-13:00


Instructor: Dr James Hollway (Graduate Institute Geneva)


Keywords: Network Dynamics, Time-stamped network data, DyNAMs, REMs



The advent of electronic communication, social media, and human sensor technologies and the digitization of many archives has generated a wealth of temporally specific relational data for social scientists to explore. Ties come with details about when they begin and, sometimes, end, giving us information about the order and duration of ties.


This workshop introduces and compares different approaches for the analysis of time-stamped network data with special attention to the dynamic network actor class of longitudinal statistical network models (DyNAMs). The goal is to provide an overview of research problems that relate to time-stamped network data, to enable participants to conduct basic analyses with the Goldfish package in R, and to introduce conceptual and practical differences between models that have been proposed, in particular, focusing on differences between actor-oriented and tie-oriented approaches.


The practical elements of the workshop (about 50%) introduce Goldfish, a new R package for the analysis of time-stamped network data. In particular, three types of models are introduced, compared, and practically applied.


1) Actor-oriented models for undirected coordination ties. Typical examples are research problems found in the political sciences (e.g., the creation and dissolution of international treaties) and economics (e.g., coordination between financial institutions) and are concerned with the creation of undirected, bilateral agreements that are the result of a coordination process.

2) Actor-oriented models for directed events. Typical examples are sequences of interaction events (e.g., phone calls) or directed transactions (e.g., financial transactions).

3) Both actor-oriented models are compared to the tie-oriented relational event model which can also be estimated with the Goldfish package.

The practical elements make use of R scripts that are distributed to participants in advance. Participants can further bring their own research problems and their own data. Based on the number of participants, a limited amount of time will be reserved to discuss these.


The Workshop will take place at Heriot-Watt University JN116 (James Nasmyth Building), 09:00-13:00. Please meet at Edinburgh Business School (EBS), Heriot-Watt University from 08:15-08:45 for arrival teas, coffees and registration. We will then walk across to the workshop suite. Book your free place at our Eventbrite page.
