internal

Provides p-values in type I, II or III anova and summary tables
for lmer model fits (cf. lme4) via Satterthwaite's degrees of freedom method. A
Kenward-Roger method is also available via the pbkrtest package. Model selection
methods include step, drop1 and anova-like tables for random effects (ranova).
Methods for Least-Square means (LS-means) and tests of linear contrasts of fixed
effects are also available.
