Exact (Restricted) Likelihood Ratio Tests for Mixed and Additive Models

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().



*** removed bug in LRTSim that led to non-sensical results.

  • now deals with testing in models where tested variance component is 0 for m, but not for mA. (Thanks, Christoph Huber-Huber!)
  • now deals correctly with models returned from lmerTest::lmer (Thanks, Lukas Meier)


*** now using Rcpp

  • removed terrible "browser()"-bug in extract.lmeDesign()
