Dear all,

Using longitudinal data at prefecture level, I conducted multilevel analyses with a random-intercept(prefecture) using menbreg command. I would like to identify autoregressive covariance, but menbreg command has no options about that, whereas "mixed", linear-regression model has. The covariance() options for menbreg seems for no meaning if the model contains one random intercept. Could you please tell me how I can take correlation structure into a generalized mixed model?

Sincerely,
Mariko
