I have been involving in causal inference analysis since 2015. We use a mixed model of decision tree and fixed effect regressions. I read your paper and could not find a reference of why, while one cannot do AB test to verify the relationship but can use observational analysis to do it. Could you share a reference please? Thank you for this insightful article!

You can definitely do an AB test to verify the causal relationship - in fact, that's the preferred method! Our platform is for situations where you didn't run an A/B test - either because you can't run as many as you'd like or you forgot - in order to give you an estimate after the fact.
