Description

Abstract: Directed Acyclic Graphs (DAG) are visual representations facilitating the rigorous investigation of causal relationships. DAGs have gained traction across multiple disciplines in recent years as useful tools for social science researchers for determining whether causal effects  may be identified in observational data and to infer the implications of causal models. This presentation begins by providing an overview of the counterfactual model of causal inference and its application to observational studies.  We then proceed to introduce DAGs and explain how they are useful in examining relationships between variables (causation, confounding, and endogenous selection). Finally, we explore how DAGs can be used to derive associations between two variables depending on the conditioning of intermediary variables. This presentation will serve to introduce DAGs to a non-specialist audience.
