# Causal Discovery with Unobserved Confounding and non-Gaussian Data

@article{Wang2020CausalDW, title={Causal Discovery with Unobserved Confounding and non-Gaussian Data}, author={Y. Samuel Wang and Mathias Drton}, journal={arXiv: Methodology}, year={2020} }

We consider the problem of recovering causal structure from multivariate observational data. We assume that the data arise from a linear structural equation model (SEM) in which the idiosyncratic errors are allowed to be dependent in order to capture possible latent confounding. Each SEM can be represented by a graph where vertices represent observed variables, directed edges represent direct causal effects, and bidirected edges represent dependence among error terms. Specifically, we assume…

This paper focuses on a subclass of linear SCMs which do not have this property, i.e., models in which observed variables can be causally affected by any subset of the sources, and are allowed to be a deterministic function of other observed variables or latent confounders.

It can be shown that causal effects among observed variables cannot be identified uniquely even under the assumptions of faithfulness and non-Gaussianity of exogenous noises, but an efficient method to identify the set of all possible causal effects that are compatible with the observational data is proposed.
