    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."""
