Enforcing\nconstraints can eliminate unwanted waves or kinks in the\nestimate, which improves its subjective appearance and can also\nimprove statistical performance. The main function scdensity()\nis very similar to the density() function in 'stats', allowing\nshape-restricted estimates to be obtained with little effort.\nThe methods implemented in this package are described in\nWolters and Braun (2017) ,\nWolters (2012) , and Hall and Huang\n(2002)\n.\nSee the scdensity() help for for full citations.", "License": "GPL-2", "Encoding": "UTF-8", "RoxygenNote": "7.3.2", "NeedsCompilation": "no", "Packaged": { "Date": "2026-06-05 07:56:13 UTC", "User": "root" }, "Author": "Mark A.
