Does anyone know why xtmixed does not allow a robust or cluster robust vce? Ditto for xtreg with maximum likelihood estimation. Does the procedure that Stata implements assures sandwich estimation?

Hi Mark/Steve and All,

I just joined statalist yesterday. I am interested in the above topic.
I did change the xtoverid.ado to myxtoverid.ado, which suggested by
Mark. TQ.

My question is, after my estimation, what command shall I use?
xtoverid or myxtoverid? I did run myxtoverid, but they said unrecognised
If I am still using xtoverid, are results already adjusted by the steps
we changed?

Please advice
