12.3 - Transportability of Causal Effects Across Populations

[@off4on]

Why put guest lectures on different playlists?

[@xinliuxg]

Thanks very much for the nice lecture. On slide 20, the graph is the same as that in slide 18, why cannot we use direct tranportability ? Thank you.

[@sudeshnasen2731]

Same query. Should the graph be different?

[@sudeshnasen2731]

Okay, I checked other papers, the diagram here is incorrect. There should be an unobserved confounder between T and X in the example of Combining Direct and Trivial transportability
