get_covbeta

variance parameters; <code>varpar = c(theta, sigma)</code>.

varpar

deviance function as a function of theta only.

devfun

At the optimum cov(beta) is available as vcov(lmer-model). This function
computes cov(beta) at non (RE)ML estimates of <code>varpar</code>.

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.
