Every 'dist_structure'\nobject is a 'dist', so the full distribution algebra (mean,\nvcov, sampler, surv, cdf) works automatically via default\nmethods that compose component-level distributions through the\ntopology. Adds structural queries: structure function\nevaluation, minimal path and cut sets, system signature,\ncritical states, dual, Birnbaum structural importance, and\nsystem reliability. Topology shortcut constructors\n(series_dist, parallel_dist, kofn_dist, bridge_dist) produce\nready-to-use dists from component dists and a chosen structure.", "License": "MIT + file LICENSE", "URL": "https://github.com/queelius/dist.structure", "BugReports": "https://github.com/queelius/dist.structure/issues", "Encoding": "UTF-8", "Language": "en-US", "Roxygen": "list(markdown = TRUE)", "RoxygenNote": "7.3.3", "VignetteBuilder": "knitr", "Config/testthat/edition": "3", "Repository": "https://queelius.r-universe.dev", "Date/Publication": "2026-10-28 05:52:57 UTC", "RemoteUrl": "https://github.com/queelius/dist.structure", "RemoteRef": "HEAD", "RemoteSha": "fea129e92424cc337ccd8b7eb2475c9b24f3c1bf", "NeedsCompilation": "no", "Packaged": { "Date": "2026-10-28 09:13:33 UTC", "User": "root" }, "Author": "Alexander Towell [aut, cre] (ORCID:\n)", "Maintainer": "Alexander Towell ", "_user": "queelius", "_type": "src", "_file": "dist.structure_0.5.1.tar.gz", "_fileid": "https://r2.ropensci.org/deac08b1891d80e75087d87cb0a672354e1277662f5ef7b22376611ffaf55c3b", "_filesize": 270683, "_sha256": "deac08b1891d80e75087d87cb0a672354e1277662f5ef7b22376611ffaf55c3b", "_expires": "2027-02-05T09:16:40.000Z", "_created": "2026-10-28T09:13:33.000Z", "_published": "2026-10-28T09:16:42.655Z", "_upstream": "https://github.com/queelius/dist.structure", "_status": "success", "_maintainer": { "name": "Alexander Towell", "email": "lex@metafunctor.com", "login": "queelius", "orcid": "0000-0001-6443-9897", "twitter": "@queelius", "description": "Alexander Richard Towell (Alexander Towell / Alex Towell; queelius).
