Dear all,
In glmmTMB we have these nice heterogeneous variances models like compound
symmetry, ar1, toeplitz and unstructured, for the covariance matrix over
time, say. For a course I'm teaching, I would also like to discuss the more
"simple" homogeneous variances models with compound symmetry, ar1, etc.
These can be estimated with e.g. package nlme. But why are these not
available in glmmTMB? Or are they, and should I use a particular syntax?
Best regards,
Ben.
