vcov {mvMORPH}R Documentation

Calculate variance-covariance matrix for a fitted object of class 'mvgls'

Description

Returns the variance-covariance matrix of the coefficients or the traits.

Usage


## S3 method for class 'mvgls'
vcov(object, ...)

Arguments

object

an object of class 'mvgls' obtained from a mvgls or mvols fit.

...

additional arguments for methods function. See details below.

Details

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).

Value

A matrix of the estimated covariances between the parameter estimates (of type "coef", "covariance", or "precision").
