Statistical Undecidability in Linear, Non-Gaussian Causal Models in the Presence of Latent Confounders
NeurIPS 2021poster
If causal relationships are linear and acyclic and noise terms are independent and Gaussian, causal orientation is not identified from observational data --- even if faithfulness is satisfied (Spirtes et al., 2002). Shimizu et al. (2006) showed that acyclic, linear, {\bf non}-Gaussian (LiNGAM) causa…
