- Abstract: Causal discovery algorithms aims at untangling complex causal relationships
using observational data only. Here, we introduce new causal discovery
algorithms based on staged tree models, which can represent complex and
non-symmetric causal effects. To demonstrate the efficacy of our algorithms, we
introduce a new distance, inspired by the widely used structural interventional
distance, to quantify the closeness between two staged trees in terms of their
corresponding causal inference statements. A simulation study highlights the
efficacy of staged trees in uncovering complex, asymmetric causal relationship
from data and a real-world data application illustrates their use in a
practical causal analysis.

We propose an efficient linear program to derive the upper and lower bounds of the causal effect.
We show that our bounds are consistent in the sense that as the entropy of unobserved confounders goes to zero, the gap between the upper and lower bound vanishes.
