    Smile SEM identification question




    For the identification of P(Y=y|do(X=x)), one can condition on a set which has no descendants of X and d-separates all back-door paths. What would be the corresponding graphical criteria for the identification of P(Y=y|do(X=x),do(Z=z))? In particular, I have a mediation model, so I'm interested in the identification of P(Y=y|do(T=t),do(M=m))

    Hi Lazar,

    Thank you for your response. We did use DAGitty to find adjustment sets. I'll scroll through DAGitty documentation.. maybe there'll be an explanation there.
