CHDH Seminar Series 2020: Empirical Dynamic Modeling Approaches to Causal Inference — Michael Zyphur (Part 2)
Presenter: Michael Zyphur
Date: Monday 16 March
Time: 12 - 1 PM
Location: Lowe Theatre (Room 103 Redmond Barry Building, University of Melbourne)
Seminar Description: Experiments and model-based regressions have been the two dominant methodological workhorses for over 60 years in the social and health sciences. However, these approaches have limitations that make them unsuitable for modeling complex dynamic systems. These systems involve interactions and feedback loops that can produce seemingly unpredictable behavior that is hard to study experimentally and arguably even harder to model using typical regression methods. As an alternative, physical sciences such as ecology have recently witnessed the advent of revolutionary new methods designed to study such complex dynamic systems. Referred to as empirical dynamic modeling or EDM, these methods allow 1) characterizing the complexity of a system and the degree of nonlinearity that defines its evolution over time, while also enabling 2) distinguishing correlation from causation using a non-parametric method for causal inference (i.e., a truly data-driven method for causal discovery). My talk introduces EDM and applies it to study the relationship between daily temperate and crime in Chicago, showing a causal effect of temperature on crime but not the reverse -- there are juicier results about companies and individual emotions that I can also describe after the initial talk. By using new methods such as EDM, social and health scientists will be better equipped to study a variety of real-world complex dynamic systems.
