Daniel is absolutely right. I should have mentioned that. You can also find a nice set of presentation slides on correlated random effects by Jeffrey Wooldridge at http://www.iza.org/conference_files/...linear_iza.pdf

This claim is not true. Victoria should not "look" at the data, but let Stata do this for her.

webuse psidextract
bys id (t) : assert ed[_n] == ed[1]

indicates that indeed ed does not change over time within each individual.

There should also be no need to be searching the internet for examples, as following the link in

help xthtaylor

to the manual entry provides illustrating examples along with the formal statistical background.

Hi, Daniel

I am very new on panel data analysing. it seemed that you know a lot on hybrid models. I am wondering is it possible to create a ordinal logistic hybrid model with stata? I will appreciate it very much if you would like to offer me some suggestions.

Best wishes
Olivia
