get_covbeta function

Compute cov(beta) as a Function of varpar of an LMM

Compute cov(beta) as a Function of varpar of an LMM

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

get_covbeta(varpar, devfun)

Arguments

  • varpar: variance parameters; varpar = c(theta, sigma).
  • devfun: deviance function as a function of theta only.

Returns

cov(beta) at supplied varpar values.
