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 |
... |
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").
