The data\nare used to estimate simultaneously systematic error (bias) and\nrandom error (imprecision). Observed measurements for each\nmethod or device are assumed to be linear functions of the\nunknown true values and the errors are assumed normally\ndistributed. Pairwise calibration curves and plots can be\neasily generated. Unlike the 'ncb.od' function, the 'omx'\nfunction builds a one-factor measurement error model using\n'OpenMx' and allows missing values, uses full information\nmaximum likelihood to estimate parameters, and provides both\nlikelihood-based and bootstrapped confidence intervals for all\nparameters, in addition to Wald-type intervals.", "License": "GPL (>= 2)", "NeedsCompilation": "no", "Packaged": { "Date": "2026-05-14 08:02:20 UTC", "User": "root" }, "Config/pak/sysreqs": "make", "Repository": "https://rabilon.r-universe.dev", "Date/Publication": "2023-08-29 14:30:47 UTC", "RemoteUrl": "https://github.com/cran/merror", "RemoteRef": "HEAD", "RemoteSha": "9b606d2e3ed3b6f89df35c0a4e73a5b8b50584a2", "MD5sum": "2b2455a4df50924802afedb956acc14d", "_user": "rabilon", "_type": "src", "_file": "merror_3.0.tar.gz", "_fileid": "52d86570c78892344785dda4d0d79e010f671148643f4d7c852d0c8791646dfc", "_filesize": 246852, "_sha256": "52d86570c78892344785dda4d0d79e010f671148643f4d7c852d0c8791646dfc", "_created": "2026-05-14T08:02:20.000Z", "_published": "2026-05-22T08:40:20.934Z", "_distro": "noble", "_jobs": [ { "job": 77345442022, "time": 197, "config": "linux-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "6989971898" }, { "job": 77345442008, "time": 151, "config": "linux-release-x86_64", "r": "4.6.0", "check": "OK", "artifact": "6989959783" }, { "job": 77345441824, "time": 204, "config": "macos-oldrel-arm64", "r": "4.5.3", "check": "OK", "artifact": "7010889261" }, { "job": 77345441912, "time": 201, "config": "macos-release-arm64", "r": "4.6.0", "check": "OK", "artifact": "6989963923" }, { "job": 77345441800, "time": 242, "config": "source", "r": "4.6.0", "check": "OK", "artifact": "6989917307" }, { "job": 77345441324, "time": 115, "config": "wasm-release", "r": "4.6.0", "check": "OK", "artifact": "7156359637" }, { "job": 77345441998, "time": 110, "config": "windows-devel", "r": "4.7.0", "check": "OK", "artifact": "6989948700" }, { "job": 77345442068, "time": 107, "config": "windows-oldrel", "r": "4.5.3", "check": "OK", "artifact": "6989947784" }, { "job": 77345441910, "time": 106, "config": "windows-release", "r": "4.6.0", "check": "OK", "artifact": "6989947099" } ], "_buildurl": "https://github.com/r-universe/rabilon/actions/runs/25848909230", "_status": "success", "_host": "GitHub-Actions", "_upstream": "https://github.com/cran/merror", "_commit": { "id": "9b606d2e3ed3b6f89df35c0a4e73a5b8b50584a2", "author": "Richard A.
