devfun_vp: Compute Deviance of an LMM as a Function of Variance Parameters
Description
This function is used for extracting the asymptotic variance-covariance matrix
of the variance parameters.
Usage
devfun_vp(varpar, devfun, reml)
Arguments
varpar
variance parameters; varpar = c(theta, sigma)
.
devfun
deviance function as a function of theta only.
reml
if TRUE
the REML deviance is computed;
if FALSE
, the ML deviance is computed.
Value
the REML or ML deviance.
