New to psychological network analysis? Looking for an overview of the literature, or tutorials on how to estimate network models? This site contains a list of introduction and tutorial papers, articles, and blog posts. Please help me fill this section and send me papers, blogs, and other suggestions!
- The best starting point to pick up both network theory and network methodology are the network analysis workshops we have been giving. All materials – including slides, R-syntax, example data, and references – are available here for free. Feel free to contact me if you are interested to host a workshop at your University! The workshops cover network estimation, inference, and accuracy of both cross-sectional and time-series network models.

- Jonas Haslbeck: Mixed graphical models (MGM). In contrast to the Ising Model (binary data) and the Gaussian Graphical Model (Gaussian data), MGM can feature different types of variables in the same network.
