Thanks Martin,
I would like to have the regression output (especially the clustered standard errors in "Result 2" not those in "Result 1") in my -outreg2- file as shown below:
------------------------------------------------------------------------
------
| Robust
__00000G | Coef. Std. Err. z P>|z| [95% Conf.
Interval]
-------------+----------------------------------------------------------
------
__00000I | .0134284 .0153607 0.87 0.382 -.016678
.0435348
__00000R | -.0022268 .0026627 -0.84 0.403 -.0074456
.002992
__00000U | -2.99e-06 .0000158 -0.19 0.851 -.000034
.0000281
__00000E | 4.651151 .0101982 456.08 0.000 4.631163
4.671139
------------------------------------------------------------------------
I would also like to know if there is a way that I can change those temporary names (_00000I, _00000R, _00000U, 00000E) to label names (k, cap, rec, _cons) with -outreg2-.
Regards,
Kelvin

Which additional part of "Results 2" do you want to see in your -outreg2-
file? The return list only gives you
scalars:
r(estatdf) = 1
r(estat) = 9.760027575966824
r(estatp) = .0017834723530583
r(jdf) = 2
r(jp) = .4366703186006444
r(j) = 1.657153576564876
and some of them are already present in your call to -outreg2-...

Betreff: st: Can I produce a regression output with -outreg2- after
-xtoverid2, noisily- ? and temporary names query.
Dear All,
I would like to know if I can produce a regression output with -outreg2-
in LaTeX after-xtoverid2, noisily cl(id)- command. When I ran the
following commands, I only managed to get the "Results 1" from -
xtivreg, re - but not "Result 2" from -xtoverid, noisily cl(id)-. I
would also like to know if there is a command that I can use to change
the temporary names to my variable label names after xtoverid. Thanks in
advance.
Commands:
net install xtoverid2,
from(http://www-personal.umich.edu/~nicholsa/stata)
webuse abdata, clear
xtivreg ys (k = emp wage cap), re
xtoverid2, noisily cl(id)
outreg2 using myfile, tex bdec(3) tdec(2) alpha(0.001, 0.01, 0.05) label
ctitle(test) adds("Endogeneity Pvalue", `r(estatp)', "FE vs RE",
`r(j)',"FE vs RE pvalue", `r(jp)' )
Results 1:
