They are not weights, but observation numbers within levels of id.

Stata probably won`t like the line "bys id : replace begin[2]=end[1]" and
complain that "weights (are) not allowed"...

Try

   expand 2
   bys id : replace begin[2]=end[1]
   bys id (begin) : replace end[2]=.
   bys id (begin) : replace cens[2]=1

Hi,

Does anyone know how I can add a new record for an id in a long form dataset?
Specifically , I have a dataset with the following structure

id	begin 	end		cens
1	1997	2006	   0
2 	1997	2003	   0
3	1997	2004	   0
3	2004	2007          0
4	1997	2006	   0

and I want to add an additional record for each id in the following manner

id	begin	end		cens
1	1997	2006	    0
1	2006	   .		    1	
2  	1997	2003           0
2      2003	    .   	    1
3	1997	2004   	    0
3	2004	2007	    0
3	2007          .		    1
4	1997	2006	    0
4	2006	   .		    1


Thanks in advance

Regards,
Marcus
