The method decomposes a\ntarget potential into a smooth component f(x) and a non-smooth\nconvex component g(x), approximating only g(x) via its\nMoreau-Yosida envelope while retaining exact gradient\ninformation for f(x). This approach, based on the methodology\ndescribed in Shukla, Vats, and Chi (2025)\n, yields improved Hamiltonian\nconservation over full-potential smoothing approaches. The\npackage provides generalized routines accepting user-defined\nprobability density functions, log-likelihoods, priors, and\nproximal operators, together with automated hyperparameter\ntuning for the Moreau-Yosida regularization parameter, Markov\nchain Monte Carlo convergence diagnostics, effective sample\nsize computation, and model evaluation metrics including the\nAkaike information criterion and Bayesian information\ncriterion.", "License": "GPL (>= 2)", "Encoding": "UTF-8", "RoxygenNote": "7.3.3", "Config/testthat/edition": "3", "NeedsCompilation": "no", "Packaged": { "Date": "2026-09-21 09:42:56 UTC", "User": "root" }, "Author": "Shikhar Tyagi [aut, cre] (ORCID:\n), Arvind Pandey [aut],\nBhupendra Singh [aut], Vrijesh Tripathi [aut]", "Maintainer": "Shikhar Tyagi ", "Repository": "https://shikhartyagi.r-universe.dev", "Date/Publication": "2026-08-21 12:40:09 UTC", "RemoteUrl": "https://github.com/cran/pHMC", "RemoteRef": "HEAD", "RemoteSha": "70429eb55b931a72f4a362185b64014d3d82a1be", "_user": "shikhartyagi", "_type": "src", "_file": "pHMC_0.1.0.tar.gz", "_fileid": "https://r2.ropensci.org/e800f2b06d18dafa94b84568bb7e8f52c064788b682278f066601f7cc033bb02", "_filesize": 190503, "_sha256": "e800f2b06d18dafa94b84568bb7e8f52c064788b682278f066601f7cc033bb02", "_expires": "2026-12-30T09:45:59.000Z", "_created": "2026-09-21T09:42:56.000Z", "_published": "2026-09-21T09:46:01.795Z", "_jobs": [ { "job": 106285698276, "time": 145, "config": "linux-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "10631559653" }, { "job": 106285698351, "time": 113, "config": "linux-release-x86_64", "r": "4.6.1", "check": "OK", "artifact": "10631059124" }, { "job": 106285698409, "time": 117, "config": "macos-oldrel-arm64", "r": "4.5.3", "check": "OK", "artifact": "10630814866" }, { "job": 106285698282, "time": 104, "config": "macos-release-arm64", "r": "4.6.1", "check": "OK", "artifact": "10631413241" }, { "job": 106284346516, "time": 283, "config": "source", "r": "4.6.1", "check": "OK", "artifact": "10631103771" }, { "job": 106285698257, "time": 100, "config": "wasm-release", "r": "4.6.0", "check": "OK", "artifact": "10631878612" }, { "job": 106285698456, "time": 75, "config": "windows-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "10631093953" }, { "job": 106285698493, "time": 74, "config": "windows-oldrel-x86_64", "r": "4.5.3", "check": "OK", "artifact": "10631878531" }, { "job": 106285698331, "time": 76, "config": "windows-release-x86_64", "r": "4.6.1", "check": "OK", "artifact": "10631049256" } ], "_host": "GitHub-Actions", "_buildurl": "https://github.com/r-universe/shikhartyagi/actions/runs/35584394920", "_status": "success", "_upstream": "https://github.com/cran/pHMC", "_commit": { "id": "70429eb55b931a72f4a362185b64014d3d82a1be", "author": "Shikhar Tyagi ", "committer": "cran-robot ", "message": "version 0.1.0\n", "time": 1787316009 }, "_maintainer": { "name": "Shikhar Tyagi", "email": "shikhar1093tyagi@gmail.com", "login": "shikhartyagi", "description": "Lecturer, Department of Mathematics and Statistics, The University of the West Indies, Trinidad and Tobago.
