Capabilities for enhanced local linear regression\nfunction and derivative estimation are included, as well as an\nasymptotically correct iterated data sharpening estimator for\nany degree of local polynomial regression estimation. A\ncross-validation-based bandwidth selector is included which, in\nconcert with the iterated sharpener, will often provide\nsuperior performance, according to a median integrated squared\nerror criterion. Sample data sets are provided to illustrate\nfunction usage.", "LazyLoad": "true", "LazyData": "true", "ZipData": "no", "License": "Unlimited", "NeedsCompilation": "yes", "Packaged": { "Date": "2026-05-15 06:54:56 UTC", "User": "root" }, "Repository": "https://wjbraun.r-universe.dev", "Date/Publication": "2021-03-30 06:40:02 UTC", "RemoteUrl": "https://github.com/cran/sharpData", "RemoteRef": "HEAD", "RemoteSha": "e0e336ee024041f7b8d7b29e477fa279dbdc95c8", "MD5sum": "8f9114b06fa051e9a3b4c51f06b15e13", "_user": "wjbraun", "_type": "src", "_file": "sharpData_1.4.tar.gz", "_fileid": "2d897423fb0fcdc1ef04b16c2f30a2f2c8f80c9e7184e024f420ecb611c9dcfa", "_filesize": 120934, "_sha256": "2d897423fb0fcdc1ef04b16c2f30a2f2c8f80c9e7184e024f420ecb611c9dcfa", "_created": "2026-05-15T06:54:56.000Z", "_published": "2026-06-02T19:51:42.732Z", "_distro": "noble", "_jobs": [ { "job": 79158852103, "time": 109, "config": "linux-devel-arm64", "r": "4.7.0", "check": "OK", "artifact": "7011779307" }, { "job": 79158852028, "time": 101, "config": "linux-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "7011777484" }, { "job": 79158851915, "time": 119, "config": "linux-release-arm64", "r": "4.6.0", "check": "OK", "artifact": "7011781074" }, { "job": 79158851857, "time": 94, "config": "linux-release-x86_64", "r": "4.6.0", "check": "OK", "artifact": "7011776027" }, { "job": 79158851695, "time": 85, "config": "macos-oldrel-arm64", "r": "4.5.3", "check": "OK", "artifact": "7011774752" }, { "job": 79158851918, "time": 347, "config": "macos-oldrel-x86_64", "r": "4.5.3", "check": "OK", "artifact": "7011833121" }, { "job": 79158851991, "time": 92, "config": "macos-release-arm64", "r": "4.6.0", "check": "OK", "artifact": "7011775536" }, { "job": 79158851876, "time": 168, "config": "macos-release-x86_64", "r": "4.6.0", "check": "OK", "artifact": "7011792215" }, { "job": 79158850756, "time": 111, "config": "source", "r": "4.6.0", "check": "OK", "artifact": "7011754251" }, { "job": 79158850829, "time": 95, "config": "wasm-release", "r": "4.6.0", "check": "FAIL", "artifact": "" }, { "job": 79158851958, "time": 89, "config": "windows-devel", "r": "4.7.0", "check": "OK", "artifact": "7011774867" }, { "job": 79158851906, "time": 75, "config": "windows-oldrel", "r": "4.5.3", "check": "OK", "artifact": "7011771876" }, { "job": 79158851705, "time": 109, "config": "windows-release", "r": "4.6.0", "check": "OK", "artifact": "7011778923" } ], "_buildurl": "https://github.com/r-universe/wjbraun/actions/runs/25904745666", "_status": "success", "_host": "GitHub-Actions", "_upstream": "https://github.com/cran/sharpData", "_commit": { "id": "e0e336ee024041f7b8d7b29e477fa279dbdc95c8", "author": "W.J.
