Dear all,
I am trying to calculate next year value based on a panel data like below:
ID Year Value
1 1993 0.29
1 1994 0.65
1 1995 0.79
2 1993 1.23
2 1994 1.56
3 2001 0.98
3 2002 0.73
What I would want is to calculate lead(value). For example:
ID Year Value Value_nxt
1 1993 0.29 0.65
1 1994 0.65 0.79
1 1995 0.79
...................
Below is my code. Somehow it's not working right. Can anyone please tell me where went wrong and how I can fix this? Much appreciated!
proc sort data=have; by ID year; run;
data want; set have; by ID year;
if eof1=0 then set have (firstobs=2 rename=(value=value_nxt) ) end=eof1;
if last.ID then value_nxt=.;
run;
JOL
A small change might be enough:
if eof1=0 then set have (firstobs=2 keep=value rename=(value=value_nxt) ) end=eof1;
A small change might be enough:
if eof1=0 then set have (firstobs=2 keep=value rename=(value=value_nxt) ) end=eof1;
Yes It worked!!! Thanks a lot!
