(2025) ). Point\nestimates, either maximum pseudo-likelihood or maximum a\nposteriori, are obtained through a trust region optimization\nalgorithm, with robust standard errors from the\nGodambe-Huber-White (GHW, or sandwich) estimator, for both full\nand constrained network structures. Bayesian inference corrects\nthe pseudo-posterior through coordinate rescaling (Arena and\nMarsman (2026) ), which matches\nits covariance to the GHW covariance, and samples from it with\nthe Fisher adaptive Metropolis-adjusted Langevin algorithm\n(Titsias (2024) ). For\ncomparison, the posterior based on the full likelihood can also\nbe sampled, exactly for small networks or with the double\nMetropolis-Hastings algorithm (Liang (2010)\n). Savage-Dickey Bayes factors\ntest each pairwise interaction, computed either by sampling\nimportance resampling (Skare et al. (2003)\n) or from the posterior draws.", "License": "MIT + file LICENSE", "Copyright": "The dataset 'rads2' is licensed under CC BY 4.0; see file\nCOPYRIGHTS.", "URL": "https://jupepis.github.io/dmrfit/,\nhttps://github.com/jupepis/dmrfit", "BugReports": "https://github.com/jupepis/dmrfit/issues", "VignetteBuilder": "knitr", "Encoding": "UTF-8", "LazyData": "true", "Roxygen": "list(markdown = TRUE)", "RoxygenNote": "7.3.3", "Repository": "https://jupepis.r-universe.dev", "Date/Publication": "2026-10-08 10:00:02 UTC", "RemoteUrl": "https://github.com/jupepis/dmrfit", "RemoteRef": "HEAD", "RemoteSha": "5b105d4b66c94d2498638fbda5de7b0c25ec83de", "NeedsCompilation": "yes", "Packaged": { "Date": "2026-10-19 10:16:15 UTC", "User": "root" }, "Author": "Giuseppe Arena [aut, cre] (ORCID:\n)", "Maintainer": "Giuseppe Arena ", "_user": "jupepis", "_type": "src", "_file": "dmrfit_0.1.1.tar.gz", "_fileid": "https://r2.ropensci.org/a12a84eb5420a3f99118843d36346579a7c9fa36981922ffea851029999d1235", "_filesize": 1367799, "_sha256": "a12a84eb5420a3f99118843d36346579a7c9fa36981922ffea851029999d1235", "_expires": "2027-01-27T10:28:24.000Z", "_created": "2026-10-19T10:16:15.000Z", "_published": "2026-10-19T10:28:25.994Z", "_buildurl": "https://github.com/r-universe/jupepis/actions/runs/39235500277", "_status": "success", "_host": "GitHub-Actions", "_jobs": [ { "job": 118006354742, "time": 156, "config": "linux-devel-arm64", "r": "4.7.0", "check": "OK", "artifact": "12179552189" }, { "job": 118006354889, "time": 220, "config": "linux-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "12178843601" }, { "job": 118006354899, "time": 158, "config": "linux-release-arm64", "r": "4.6.1", "check": "OK", "artifact": "12179412231" }, { "job": 118006354655, "time": 181, "config": "linux-release-x86_64", "r": "4.6.1", "check": "OK", "artifact": "12179712162" }, { "job": 118006354631, "time": 187, "config": "macos-oldrel-arm64", "r": "4.5.3", "check": "OK", "artifact": "12178858293" }, { "job": 118006354780, "time": 642, "config": "macos-oldrel-x86_64", "r": "4.5.3", "check": "OK", "artifact": "12179223569" }, { "job": 118006354823, "time": 266, "config": "macos-release-arm64", "r": "4.6.1", "check": "OK", "artifact": "12178913375" }, { "job": 118006354769, "time": 519, "config": "macos-release-x86_64", "r": "4.6.1", "check": "OK", "artifact": "12179002760" }, { "job": 118003571313, "time": 410, "config": "source", "r": "4.6.1", "check": "OK", "artifact": "12178892820" }, { "job": 118006354640, "time": 134, "config": "wasm-release", "r": "4.6.0", "check": "OK", "artifact": "12179646988" }, { "job": 118006354827, "time": 394, "config": "windows-devel-arm64", "r": "4.7.0", "check": "OK", "artifact": "12179457700" }, { "job": 118006354750, "time": 227, "config": "windows-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "12179916551" }, { "job": 118006354707, "time": 211, "config": "windows-oldrel-x86_64", "r": "4.5.3", "check": "OK", "artifact": "12179347368" }, { "job": 118006354667, "time": 427, "config": "windows-release-arm64", "r": "4.6.1", "check": "OK", "artifact": "12178579432" }, { "job": 118006354911, "time": 200, "config": "windows-release-x86_64", "r": "4.6.1", "check": "OK", "artifact": "12179762061" } ], "_upstream": "https://github.com/jupepis/dmrfit", "_commit": { "id": "5b105d4b66c94d2498638fbda5de7b0c25ec83de", "author": "Giuseppe Arena ", "committer": "GitHub ", "message": "Merge pull request #8 from jupepis/release-0.1.1\n\ndmrfit 0.1.1", "time": 1791453602 }, "_maintainer": { "name": "Giuseppe Arena", "email": "g.arena@uva.nl", "login": "jupepis", "bluesky": "@giuseppearena.bsky.social", "orcid": "0000-0001-5204-3326", "description": "Hello there !
