Returns variance-covariance matrix of coefficients in a GLLVM.
Returns the variance-covariance matrix of the parameters from a GLLVM. If the variance-covariance matrix was not calculated after model fitting, this function will have to calculate the variance-covariance matrix, which may be computational intensive for a large number of species and/or sites.
## S3 method for class 'gllvm' vcov(object)
object |
an object of class 'gllvm'. |
Calculates the variance-covariance matrix of a GLLVM object using se.gllvm
, which may be computational intensive with many parameters.The parameters might have unintuitive names. Fixed-effects coefficients are labled "b", and are ordered per species as: 1) intercepts 2) fixed-effects slopes. Coefficients of the latent variables are labled "lambda" (linear coefficients) or "lambda2".
