## S3 method for class 'hlme'
VarCov(x)
## S3 method for class 'lcmm'
VarCov(x)
## S3 method for class 'Jointlcmm'
VarCov(x)
## S3 method for class 'multlcmm'
VarCov(x)

Arguments

x

an object of class hlme, lcmm, multlcmm or Jointlcmm

Value

a matrix containing the variance-covariance of the estimates. For the parameters of the matrix of variance-covariance of the random effects, the Cholesky transformed parameters are considered so that VarCov provides the covariance matrix of function estimates with cholesky=TRUE.
