Hi all,

I have a few questions regarding my code below:

1- Using
Code:
xtset dep time
gives me this error:
Code:
. xtset dep time
repeated time values within panel
r(451);
end of do-file
r(451);
Then I use
Code:
xtset dep
it works. Is there any problem here? I have an unbalanced dataset.

2_ Using this code:
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:
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
gives me this error:
Code:
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
JL
