Sorry, I had a problem with the previous email . This is the correct one


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
 
Having done that I will be able to notify Stata that I have monthly series

Tzaloupas

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
http://www.stata.com/statalist/archive/2013-01/msg01346.html

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