Testability of Instrumental Variables in Linear Non-Gaussian Acyclic Causal Models
This paper investigates the problem of selecting instrumental variables relative to a target causal influence [Formula: see text] from observational data generated by linear non-Gaussian acyclic causal models in the presence of unmeasured confounders. We propose a necessary condition for detecting v...
