Variance-Covariance matrix

I have a question regarding the extraction of some parts of the analysis results as we wanted to perform a kind of global test. Is there any possibility to extract the whole vector of fixed effects estimates and the corresponding variance-covariance matrix? For the first one we can use results$coef I guess. But I didn’t find any possibility for the variance-covariance matrix.

Many thanks in advance for your reply!

Hi Anna,

The easiest way to get the variance-covariance matrix would be to set the save model flag to true and then loop through the saved models using something like vcov. Sorry there is not a more straight forward option.
