get_covbeta R Documentation
Compute covariance of fixed effect parameters as a function of variance parameters of a linear mixed model
Description
At the optimum the covariance is available as vcov(lmer-model). This function
computes cov(beta) at non (RE)ML estimates of varpar.
Usage
get_covbeta(varpar, devfun)
Arguments
varpar
variance parameters; varpar = c(theta, sigma).
devfun
deviance function as a function of theta only.
Value
The covariances matrix of the fixed effects at supplied varpar values.
