Graphical causality
WebApr 30, 2024 · Introduction. Graphical models provide a powerful mathematical framework to represent dependence among variables. Directed edges in a graphical model further represent marginal and conditional dependencies that may be interpreted as causality (Lauritzen, 1996; Spirtes et al., 2000; Koller and Friedman, 2009; Pearl, 2009; Dawid, … http://faculty.ist.psu.edu/vhonavar/Courses/causality/Causal-inference.pdf

WebIt states that under certain circumstances, for a set of variables W, we can estimate the the causal influence of X on Y with respect to a causal graphical model using the equation. P ( Y ∣ d o ( X)) = ∑ W P ( Y ∣ X, W) P ( W) The criterion for W to exist is sometimes called the backdoor criterion.

WebCausal Inference with Graphical Models¶.
