devfun_vp

Compute Deviance of an LMM as a Function of Variance Parameters

This function is used for extracting the asymptotic variance-covariance matrix of the variance parameters.

devfun_vp(varpar, devfun, reml)

`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.

the REML or ML deviance.
