I've encountered lots of causal inference terms and jargons (under the Neyman-Rubin potential outcome framework), and I had a question regarding how Pearl's DAG restrictions relate to ignorability and unconfoundedness.
Is the "back-door" the same as ignorability?
And is the "front-door" the same as unconfundedness?
My motivation: Wikipedia page on ignorability seems to suggest that Pearl's back-door is a type of ignorability.
Pearl devised a simple graphical criterion, called back-door, that entails ignorability and identifies sets of covariates that achieve this condition
