In the first stage, neighborhood selection via\nthe Lasso constructs a sparse undirected skeleton. In the\nsecond stage, the Fast Causal Inference (FCI) algorithm orients\nedges on this reduced graph, producing a Partial Ancestral\nGraph (PAG) that accounts for latent confounders. The method is\nconsistent under sparsity assumptions and substantially faster\nthan standard FCI and RFCI in high dimensions.
