Dear members,
I want to examine the multilevel model's error covariance structure
(e.g., identity, unstructured) when using "xtmixed" in STATA.
I know STATA allows me to examine 1. independent; 2.exchangeable;
3.identity; 4. unstructured.
Could I examine "1st order auto-regressive" with "xtmixed" in STATA ??
If yes, what is the syntax for that?
Many thanks.
Mark
