Compute deviance of a linear mixed model 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.
