Returns the variance-covariance matrix of the coefficients or the traits.
# S3 method for mvgls
vcov(object, ...)
A matrix of the estimated covariances between the parameter estimates (of type "coef", "covariance", or "precision").
an object of class 'mvgls' obtained from a mvgls
or mvols
fit.
additional arguments for methods function. See details below.

The vcov
function returns by default the variance-covariance matrix of the main parameters of a fitted model object. The main parameters are the coefficients (this correspond to the argument type="coef"
; see also coef.mvgls
). With type="covariance"
, the vcov.mvgls
function returns the estimated traits covariance matrix (possibly regularized for PL approaches) while type="precision"
return the precision matrix (i.e. the inverse of the covariance).
