In the first stage, neighborhood selection via the Lasso constructs a sparse undirected skeleton. In the second stage, the Fast Causal Inference (FCI) algorithm orients edges on this reduced graph, producing a Partial Ancestral Graph (PAG) that accounts for latent confounders. The method is consistent under sparsity assumptions and substantially faster than standard FCI and RFCI in high dimensions. See Pal, Ghosh, and Yang (2025) <doi:10.48550/arXiv.2507.00173> for the underlying theory.https://github.com/r-universe/djghosh1123/actions/runs/26876466623Wed, 03 Jun 2026 05:12:21 GMTPFCI0.1.1successhttps://djghosh1123.r-universe.devhttps://github.com/djghosh1123/pfciPFCIdemo.RmdPFCIdemo.htmlGetting Started with PFCI2026-05-28 20:20:292026-06-03 05:06:07
