vcov-multcomp: Variance-Covariance Matrix for a Fitted Object

Description

Returns the variance-covariance matrix of a fitted object. For internal use.

Usage

# S3 method for mmm2
vcov(object, return.null = TRUE, adjust.residuals = TRUE,
  robust = FALSE, ...)
# S3 method for ls.lvmfit
vcov(object, return.null = TRUE,
  adjust.residuals = TRUE, robust = FALSE, ...)

Arguments

object

a mmm2 or ls.lvmfit object.

return.null

if TRUE return a matrix filled with NA.

adjust.residuals

small sample adjustement.

robust

should robust standard error be used? Otherwise rescale the influence function with the standard error obtained from the information matrix.
