Dear Matias,
-outreg- works for me after -ml- (example below).
Possible causes of your problem
1. -outreg- must follow -ml maximize- and NOT -ml model-
2. I believe there may be a small bug for which I would be grateful if there
were independent confirmation when the option -append- is specified and the
file path contains a blank space e.g.
outreg using "C:\My Documents\outreg_and_ml.txt", append bracket se 3aster
coefastr addstat("Prob > chi2" , e(p))
Returns
invalid 'Documents'
Same problem if compounds quotes are used.
Strangely enough, it seems to work great when the option -replace- is
specified regardless of blanks.
As a temporary fix, it does work when there is no blank in the path e.g.
outreg using "c:\data\outreg_and_ml.txt", append bracket se 3aster coefastr
addstat("Prob > chi2" , e(p))
3. It might work for my ml and not for yours. I have no idea of what -ml
model- you are using. I could not test them all :)

Separately, I want to thank Nick Cox for his canned solution for better
lables for dummy variables
http://www.stata.com/statalist/archive/2002-10/msg00036.html
His canned solution can be usefully employed in this situation too (provided
that you have no interaction effects)
Moreover, to complete my answer to Matias, -reformat- works too.
Both -reformat- and -outreg- have strength and weaknesses. It is certainly
possible to write something that sums the strengths of both, but I think it
would be huge work.
And now, as promised here is my example of -outreg- that works after -ml
maximize-
use mydata, clear
constraint define 1 var1=1
keep if sex=="male": sex
program define mylikelihood
version 8.0
args lnf theta1 theta2
* omitted
end
char _dta[omit] prevalent
xi: ml model lf mylikelihood (exbeta: income= var1 i.var2 var3 var4 var5
i.var6 i.var7 var8 and so on) (sigma:), constraints(1)
ml check
ml search
ml maximize, difficult
outreg using "c:\data\outreg_and_ml.txt", replace bracket se 3aster coefastr
addstat("Prob > chi2" , e(p))
ml graph
ml clear
program drop mylikelihood
use mydata, clear
constraint define 1 var1=1
keep if sex=="female": sex
program define mylikelihood
version 8.0
args lnf theta1 theta2
* omitted
end
char _dta[omit] prevalent
xi: ml model lf mylikelihood (exbeta: income= var1 i.var2 var3 var4 var5
i.var6 i.var7 var8 and so on) (sigma:), constraints(1)
ml check
ml search
ml maximize, difficult
outreg using "c:\data\outreg_and_ml.txt", append bracket se 3aster coefastr
addstat("Prob > chi2" , e(p))
ml graph
ml clear
program drop mylikelihood
I hope it helps.
Sincerely,
Renzo Comolli
