You are more than welcome :-) Your issue is weird indeed! What do you get
with -ereturn list- after applying -xtivreg2- to your data? I mean, does
Stata populate the rest of the returned values?

Betreff: st: Re: AW: AW: ereturn list with xtivreg2
Well, curious... I have -adoupdate-d my -xtivreg2-, just to be sure.
When I run your example, I get in fact e(df_r) (thanks for pointing it
out in red!). But when I run my own command on my dataset, I do not
get anything:
. disp e(df_r)
.
This happens with and without clustering, with and without robust
s.e., with and without excluded instruments. In every one of these
cases, I do not have anything saved in e(df_r). My data are properly
-tsset-.
