Programme of the 6th SIENA workshop

23-27 January 2012
- at various city centre locations -
University of Groningen

- version of January 23, 2012 -

This workshop is about the analysis of longitudinal, group-centered network data by way of stochastic, actor-based models (Snijders, van de Bunt & Steglich, 2010), and about the analysis of peer influence processes taking place in such dynamically changing networks (Steglich, Snijders & Pearson, 2010). Objective of the workshop is that course participants develop an understanding of the models, and familiarise themselves with the use of the RSiena software for model estimation. Researchers who are in the process of collecting or analysing own longitudinal data sets are especially welcome to participate.

Since 2005, Tom Snijders and the developers' team of the SIENA software for longitudinal social network analysis have been teaching courses in Groningen/Netherlands, where the research lab is located that gave birth to this data analysis tool. For these workshops' overview page, click here.

On this page you find the programme and course material of the 2012 workshop, which will again take place in the university's Academy Building in the city centre of Groningen. Sessions generally start at 9:00 and end at 17:00, with an ample lunch break from 12:30-14:00. Teachers in 2012 will be Christian Steglich, Filip Agneessens, Marijtje van Duijn and Mark Huisman.

An overview of the workshop participants, with short biographical sketches, can be found here: Participants2012.pdf.

The latest news about the room problem is that we very likely will have to go to a different room every day. Please regard it as a bit of sightseeing in our university... From Tuesday on, we meet every morning on the stairs of the academy building at 8:50 and then jointly go to the room of the day. These rooms are added to the course days now, you can click on the address & be linked to a map showing you where the building can be found.


Preparation before the course

Course participants are expected to bring their own laptop to the course, with the R
software and some R packages pre-installed. Instructions for this are given right below.
The operating system on the laptops can be Windows (32 or 64 bit), Linux, or Mac OS;
in principle, all software we will work with is designed for platform-independence.

Please follow these steps for getting started with network analysis in R:
     1. Install R on your computer; see http://www.r-project.org/
     2. Start R while you have an internet connection.
     3. Install the course-relevant R packages:
           • open this script in a text editor,
           • copy all text, and
           • paste it into the R console window.
         This should install the R packages 'network', 'sna', 'igraph', 'coda',
         'ergm', 'RSiena', and 'RSienaTest'.
     4. Also install the visone software for visualisation on your computer;
         see http://visone.info/.

It also is a good idea to already download the course material posted below. There will
be changes of some material, but most of it will be used as it is available now.

Monday, Room A2, Academy Building (1111), Broerstraat 5

We open around 9:00 with a walk-in welcome, at 9:30 the lessons will start.
