Description: Provides nonparametric permutation tests for testing all
        or any subset of random effects in linear and nonlinear
        mixed-effects models, without requiring normality or other
        distributional assumptions on random effects or errors. Three
        distribution-free variance-component estimators are
        implemented: Variance Least Squares ('VLS'), Method of Moments
        ('MM'), and Method of Moments with First-Order Approximation
        ('MMF'). A permutation procedure is used to obtain
        finite-sample p-values. Plotting functions support data
        exploration, model evaluation, and communication of results.
        Methods are described in Uwimpuhwe, Drikvandi, and Blozis
        (2026) <doi:10.1002/sim.70605>.
