Thanks NIck for your promt reply. Yes, you are right. I need to notify Stata that I have monthly data.
In order to simplify the problem i did that
gen dummy1 = overall == "RR"
gen dummy2 = specific == "kk2"
gen dummy3=1 if dummy1==1 & dummy2==1
keep if dummy3==1
So this gives me the following matrix
UK RR kk2 01/03/2001 .
UK RR kk2 01/04/2001 3.6
UK RR kk2 01/05/2001 8
US RR kk2 01/03/2001 8.56
US RR kk2 01/04/2001 0.5
US RR kk2 01/05/2001 2.25
But here comes the problem. I need to construct and identifier, something like
1 UK RR kk2 01/03/2001 .
1 UK RR kk2 01/04/2001 3.6
1 UK RR kk2 01/05/2001 8
2 US RR kk2 01/03/2001 8.56
2 US RR kk2 01/04/2001 0.5
3 US RR kk2 01/05/2001 2.25
but I do not know how to do that. Having done

Your problems mostly come towards the end.
1. As these are panel data, -tsset- must specify a panel too.
2. You have said that these are daily data presented as DMY, but they
look like monthly data in disguise.
3. Assigning a monthly format to daily data will not change it to
monthly data, as I often point out on this list. See e.g. the thread
starting at

that I suppose it is much easier to notify Stata about my monthly data
Any suggestions on how to create this identifier?
