This course provides you with conceptual understandings, as well as tools to learn causality from data. These understandings and tools come from the rapidly developing science of causal inference. On the conceptual level, the course covers basic concepts such as causation vs. correlation, causal inference, causal identification and counterfactual. It also presents perspectives and tools to help you formalize and conceptualize causal relationships. These perspectives and tools are synergized from multiple disciplines, including statistics (e.g., Robin Causal Model or Potential Outcome Framework), computer science (e.g., Pearlian Causal Model or Causal Graph), and econometrics (e.g., identification strategies and local average treatment effect).
In this course, we will also discuss a selection of tools in causal inference. We will start with the completely randomized experiment and discuss the assignment mechanism, Fisher’s exact p-value, and Neyman’s repeated sampling approach. From then on, we will gradually relax the assumption of complete randomization and discuss situations where the complete randomization does not hold. Specifically, we will discuss the following: First, block randomization and conditional random assignment, with a focus on matching and weighting estimators; Second, non-compliance where the random assignment fails and the local average treatment effects; Third, attrition where some outcomes are missing and the bounding approach; Fourth, research designs when the assignment mechanism is unknown to us, including the difference-in-difference approach and regression discontinuity design. Moreover, in the last day of the course, we will discuss the ethics of causal inference and the assessment of the unconfoundedness assumption. As the “finale,” we will go through the most recent developments in the intersection between causal inference and machine learning, where machine learning techniques are used to address causal inference problems.
