It implements multiple bootstrap methods under the parametric, residual, and case bootstrap categories. Currently it supports fitted objects from the lme4 package.https://github.com/r-universe/marklhc/actions/runs/29231200958Tue, 05 May 2026 07:11:40 GMTbootmlm0.1.0.9000successhttps://marklhc.r-universe.devhttps://github.com/marklhc/bootmlmcompare.Rmdcompare.htmlComparing Different Multilevel Bootstrapping Methods2017-08-20 16:14:112026-05-05 07:03:14derived_quantities.Rmdderived_quantities.htmlUsing Multilevel Bootstrap for Derived Quantities2017-08-20 16:14:112026-05-05 07:03:14marklhc@gmail.com (Hok Chio (Mark) Lai)Extends the popular 'lavaan' package by adding penalized estimation capabilities. It supports penalty on individual parameters as well as the difference between parameters.https://github.com/r-universe/marklhc/actions/runs/29310019462Thu, 18 Dec 2025 16:58:19 GMTplavaan0.0.1successhttps://marklhc.r-universe.devhttps://github.com/marklhc/plavaanapproximate-invariance.Rmdapproximate-invariance.htmlApproximate Invariance with Penalized Estimation2025-12-15 14:30:492025-12-18 16:00:19penalized-fa.Rmdpenalized-fa.htmlPenalized Estimation of Cross-Loadings and Unique Covariances2025-12-15 13:55:392025-12-15 13:55:39penalized-cat.Rmdpenalized-cat.htmlPenalized Estimation with Ordinal Data and Multiple Groups2025-12-16 02:11:002025-12-16 02:11:00standard-errors.Rmdstandard-errors.htmlStandard Errors2025-12-18 16:11:052025-12-18 16:11:05
