I am using xtivreg (random effect) and I need to add the option "cluster", but
i can't!
I have tried using xtivreg2, but this command does't perform a random effect
estimation (just fixed effect and first difference), and, me, I really need a
rendom effect estimation for my model.
Is there a way to do it? that is, to have a dynamic random effect estimation+
cluster option?
Thanks
