To get the predicted result for each county, I need to get the random effect (residuals) for each county as well as their variances. However, the ranef command only produce the random effect without giving the confidence interval / variance. I would be glad if you can let me know how to produce the confidence interval of these random effects so I can calculate their confidence intervals.
ranef(fit2)
Have you tried dotplot(ranef(fit2, postVar = TRUE)) and attr(ranef(fit2, postVar = TRUE)[[1]], "postVar") ?
