The unidimensional methods include the Mean/Mean,\nMean/Sigma, Haebara, and Stocking-Lord methods for dichotomous\n(1PL, 2PL and 3PL) and/or polytomous (graded response, partial\ncredit/generalized partial credit, nominal, and multiple-choice\nmodel) items. The multidimensional methods include the least\nsquares method and extensions of the Haebara and Stocking-Lord\nmethod using single or multiple dilation parameters for\nmultidimensional extensions of all the unidimensional\ndichotomous and polytomous item response models. The package\nalso includes functions for importing item and/or ability\nparameters from common IRT software, conducting IRT true score\nand observed score equating, and plotting item response\ncurves/surfaces, vector plots, information plots, and\ncomparison plots for examining parameter drift.", "LazyLoad": "Yes", "LazyData": "Yes", "License": "GPL (>= 2)", "NeedsCompilation": "no", "Packaged": { "Date": "2026-06-06 06:29:23 UTC", "User": "root" }, "Repository": "https://bocaccio.r-universe.dev", "Date/Publication": "2017-04-26 15:36:59 UTC", "RemoteUrl": "https://github.com/cran/plink", "RemoteRef": "HEAD", "RemoteSha": "d4ce5351b4dafbb5391a672d8ad27117bec16cfb", "MD5sum": "36a2a50f68e915626e8747f73ffe8d91", "_user": "bocaccio", "_type": "src", "_file": "plink_1.5-1.tar.gz", "_fileid": "9a79cd19e2540444a48c87a5cdcfbaf8db56c7d805eeec222d742d56e13d4d49", "_filesize": 1138474, "_sha256": "9a79cd19e2540444a48c87a5cdcfbaf8db56c7d805eeec222d742d56e13d4d49", "_created": "2026-06-06T06:29:23.000Z", "_published": "2026-06-06T06:36:31.933Z", "_distro": "noble", "_jobs": [ { "job": 79857683982, "time": 375, "config": "linux-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "7452034342" }, { "job": 79857683975, "time": 141, "config": "linux-release-x86_64", "r": "4.6.0", "check": "OK", "artifact": "7452005642" }, { "job": 79857683984, "time": 200, "config": "macos-oldrel-arm64", "r": "4.5.3", "check": "OK", "artifact": "7452009098" }, { "job": 79857683979, "time": 148, "config": "macos-release-arm64", "r": "4.6.0", "check": "OK", "artifact": "7452003298" }, { "job": 79857527573, "time": 171, "config": "source", "r": "4.6.0", "check": "OK", "artifact": "7451988424" }, { "job": 79857683972, "time": 194, "config": "wasm-release", "r": "4.6.0", "check": "OK", "artifact": "7452012249" }, { "job": 79857683985, "time": 105, "config": "windows-devel", "r": "4.7.0", "check": "OK", "artifact": "7452001293" }, { "job": 79857683976, "time": 109, "config": "windows-oldrel", "r": "4.5.3", "check": "OK", "artifact": "7452001722" }, { "job": 79857683980, "time": 96, "config": "windows-release", "r": "4.6.0", "check": "OK", "artifact": "7452000289" } ], "_buildurl": "https://github.com/r-universe/bocaccio/actions/runs/27054969024", "_status": "success", "_host": "GitHub-Actions", "_upstream": "https://github.com/cran/plink", "_commit": { "id": "d4ce5351b4dafbb5391a672d8ad27117bec16cfb", "author": "Jonathan P.
