Presentation highlights include … WebMy colleagues and I have proposed a taxonomy of biases in causal inference research. We described the structure of the biases by using causal diagrams known as directed acyclic graphs or DAGs, which we cover in our book and edX course. (It is no secret that we love big DAGs.)We distinguish three types of systematic bias: confounding, selection bias, …
