The package supports uncensored (complete) and censored\ndata (right, left, interval, and progressive censoring) with\nand without covariates. It provides maximum likelihood\nestimation, standard errors, confidence intervals,\nt-statistics, p-values, Akaike Information Criterion (AIC),\nBayesian Information Criterion (BIC), a bootstrap approximation\nof the Widely Applicable Information Criterion (WAIC), k-fold\ncross-validation, variance inflation factors, R-squared,\nadjusted R-squared, Mean Squared Error (MSE), Mean Absolute\nError (MAE), Root Mean Squared Error (RMSE), an overall model\nF-test, frailty variance estimation, survival probabilities at\nuser-specified time points, median survival, expected survival\nwithin a fixed window, risk predictions, marginal predictions,\nmartingale and deviance residuals, standardized and studentized\nresiduals, leverage values, Cook's distance, Difference in Fits\n(DFFITS), Difference in Betas (DFBETAS), and a comprehensive\nsuite of diagnostic and survival plots including Kaplan-Meier\noverlays and coefficient forest plots. Random number generation\nis available for each baseline distribution and the full\nfrailty model, and a simulation study function evaluates\nparameter recovery across sample sizes and censoring scenarios.\nReferences are Lindley (1958)\n, Mugdadi (2005)\n, Bain (1974)\n, Singh, Tyagi, Singh, and\nTyagi (2025)\n,\nPandey, Singh, Tyagi, and Tyagi (2024)\n, and Tyagi, Kumar, Pandey,\nSaha, and Bagariya (2022) .", "License": "GPL-3", "Config/testthat/edition": "3", "Encoding": "UTF-8", "Language": "en-US", "RoxygenNote": "7.3.3", "VignetteBuilder": "knitr", "NeedsCompilation": "no", "Packaged": { "Date": "2026-06-19 13:58:49 UTC", "User": "root" }, "Author": "Shikhar Tyagi [aut, cre] (ORCID:\n)", "Maintainer": "Shikhar Tyagi ", "Repository": "https://shikhartyagi.r-universe.dev", "Date/Publication": "2026-06-18 17:00:02 UTC", "RemoteUrl": "https://github.com/cran/GammaFrailty", "RemoteRef": "HEAD", "RemoteSha": "6d176dd1c53552f82bc75d328891d632bf77f5c7", "MD5sum": "944aab81502420cd498f7724decb93df", "_user": "shikhartyagi", "_type": "src", "_file": "GammaFrailty_0.1.0.tar.gz", "_fileid": "b6300060d21194b55acf38a3a1c2b7762a90c59163baed2e646b7f49fceb47b8", "_filesize": 914409, "_sha256": "b6300060d21194b55acf38a3a1c2b7762a90c59163baed2e646b7f49fceb47b8", "_created": "2026-06-19T13:58:49.000Z", "_published": "2026-06-19T14:03:43.598Z", "_distro": "noble", "_jobs": [ { "job": 82364449809, "time": 162, "config": "linux-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "7751609249" }, { "job": 82364449824, "time": 183, "config": "linux-release-x86_64", "r": "4.6.0", "check": "OK", "artifact": "7751618135" }, { "job": 82364449829, "time": 249, "config": "macos-oldrel-arm64", "r": "4.5.3", "check": "OK", "artifact": "7751629578" }, { "job": 82364449827, "time": 195, "config": "macos-release-arm64", "r": "4.6.0", "check": "OK", "artifact": "7751606732" }, { "job": 82363861212, "time": 208, "config": "source", "r": "4.6.0", "check": "OK", "artifact": "7751551667" }, { "job": 82364449784, "time": 103, "config": "wasm-release", "r": "4.6.0", "check": "OK", "artifact": "7751588321" }, { "job": 82364449857, "time": 98, "config": "windows-devel", "r": "4.7.0", "check": "OK", "artifact": "7751586581" }, { "job": 82364449836, "time": 101, "config": "windows-oldrel", "r": "4.5.3", "check": "OK", "artifact": "7751586961" }, { "job": 82364449846, "time": 99, "config": "windows-release", "r": "4.6.0", "check": "OK", "artifact": "7751586296" } ], "_buildurl": "https://github.com/r-universe/shikhartyagi/actions/runs/27829933262", "_status": "success", "_host": "GitHub-Actions", "_upstream": "https://github.com/cran/GammaFrailty", "_commit": { "id": "6d176dd1c53552f82bc75d328891d632bf77f5c7", "author": "Shikhar Tyagi ", "committer": "cran-robot ", "message": "version 0.1.0\n", "time": 1781802002 }, "_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.
