Extract Variance-Covariance Matrix

extract the covariance of fixed effects, or both fixed and random effects.

Usage

# S3 method for class 'dsem'
vcov(object, which = c("fixed", "random", "both"), ...)

Arguments

object: output from dsem
which: whether to extract the covariance among fixed effects, random effects, or both
...: ignored, for method compatibility

Value

A square matrix containing the estimated covariances among the parameter estimates in the model. The dimensions dependend upon the argument which, to determine whether fixed, random effects, or both are outputted.
