What is the PSYNETS workshop…?


The workshop consists of 8 lectures taught by leading experts in the field, a symposium with applied research, as well as guided practical sessions and exercises. It will cover the foundations of network analysis, discuss the most important techniques for cross-sectional and longitudinal data analysis, and introduce novel Bayesian approaches to network analysis.

… and what will I learn?

After completing this workshop, you will be able to

1) understand the theoretical foundations behind network modeling

2) infer network topology and estimate network parameters from different sources of data

3) analyze the network structure and its stability, and

4) reflect on research aims connected to network analysis.

This workshop is FOR YOU!

This year’s edition will focus on applied aspects of network analyses. Special attention will be paid to integrating the skills acquired in the course with substantive research questions. Basic R knowledge is required for this course.

Dinner at De Ysbreeker!

There will be a dinner at De Ysbreeker at 18:00. De Ysbreeker is located along the Amstel and is one of the ~9,000 monumental buildings Amsterdam counts. Fun fact: The restaurant is named after the icebreakers (hence: “Ysbreker”) that were docked in front of the building from 1702 till 1860. The ships would clear a path through the ice covering the Amstel River towards the city of Vecht during the cold winter months. During those years the location served as a tavern for shipmates and locals of the neighborhood.

Day 5: Friday, February 2

Morning session: Q&A

During this morning session, you can work on your own data with lecturers and members from our lab aiding you in the analyses. It is also the perfect opportunity to ask any questions about the materials you might still have.

Afternoon session: Reflections on the Network Approach
