Exact (Restricted) Likelihood Ratio Tests for Mixed and Additive
Models
Description
Rapid, simulation-based exact (restricted) likelihood ratio tests
for testing the presence of variance components/nonparametric terms for
models fit with nlme::lme(),lme4::lmer(), lmeTest::lmer(), gamm4::gamm4(),
mgcv::gamm() and SemiPar::spm().
