Equilibrium Causal Models: Connecting Causal Models & Dynamical Systems

Published:

Feedback loops and cyclic relationships are a mainstay of dynamical systems modelling, yet they are conspicuously absent in much of causal inference, where Directed Acyclic Graphs (DAGs) abound. Cycles do indeed have a place in causal inference, yet, in order to understand them, it is necessary to map causal models and causal intuitions back onto dynamical systems. To do this we can make use of Equilibrium Causal Models (ECMs), causal abstractions of dynamical systems which a) allow researchers to reason about the long time-scale effects of interventions and b) can potentially be learned from cross-sectional data. In this short talk, we give a brief motivation of ECMs, discuss how they relate to contemporary issues in psychological research, and sketch a simulation study to assess the feasibility of learning cyclic causal structures in practice.

Introduction to Causal Modeling (Parts 1 and 2)

Published:

On November 7th and December 10th I gave a two part workshop to professional data scientists working at the University Medical Centre, Utrecht. The aim of the workshop was to introduce researchers to modern methods for causal modeling. Workshop materials for both days, including lecture slides and R lab materials, can be found here

Formal Theories in Psychology - What they are, why they matter, and how to build them

Published:

This hands-on workshop introduced formal theories (computational models) to a general psychology audience, covering the motivation for computational modeling approaches, examples, getting started with formalization using causal graphs, and practical coding examples. The material of the workshop was prepared jointly with Don Robinaugh and Jonas Haslbeck. All workshop materials can be found here. The full workshop abstract can be found here
