pub fn counterfactual_absent(
edges: &[NQuin],
roots: &[u64],
intervene: u64,
effect: u64,
) -> (bool, bool)Expand description
Counterfactual “had intervene been absent, would effect still have occurred?” — the
twin-network comparison of the factual world against the counterfactual do(intervene absent)
world. Returns (factual, counterfactual); if they differ, intervene was counterfactually
necessary for effect.
