Outreg2 and other issues with xtprobit

[Jade Li]

Hi all,

I have a few questions regarding my code below:

1- Using

xtset dep time

gives me this error:

. xtset dep time
repeated time values within panel
r(451);
end of do-file
r(451);

Then I use

xtset dep

it works. Is there any problem here? I have an unbalanced dataset.

2_ Using this code:

xtset dep
#delimit;
xtprobit  dep indep, vce(cluster id1 id2)
outreg2 using Results.xls,  replace  excel title("Results_1")  keep(dep) dec(3) label;
#delimit cr

so I cluster standard errors at the id-pair level. Is this correct?

3- Using outreg:

xtset dep
#delimit;
xtprobit  dep indep, vce(cluster id1 id2)
outreg2 using Results.xls,  replace  excel title("Results_1")  keep(dep) dec(3) label;
#delimit cr

gives me this error:

invalid 'replace'
r(198);
end of do-file
r(198);

Note that when I use reg the outreg2 works very well.

Thank you for your help
