How to create year series?

MR_Xishuai — Wed, 01 Oct 2014 09:45:57 GMT

Hi all,

My observations have FOUR variables: ID, DATE, year1 and year2. I want to create times series(frequency: yearly) data between year1 and year2.

I have already use proc transpose to create a variable YEAR which has year1 and year2 for each observation.

for example for observation A, if year1=1995 and year2=2006, then after the proc transpose I will have two observations A1 with YEAR=1995 and A2 with YEAR=2006.

Then I want to create all the time series observations with YEAR between 1995 and 2006. Namely, Year=1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005.

I tried to use proc expand to solve the problem(I did so with monthly data), but the code below does not work:#

proc expand data=mysample out=mysample1 From=year to=year;

by ID Date;

id YEAR;

convert YEAR;

run;

The code does not work. Is it because I should not use Proc expand or is there something wrong with the code? Or could anyone tell how to solve the problem?

Many thanks!

Hi Xishuai,

Not sure if I understand right the structure of your data.

Can you provide an example of what your data looks like and the format that you need it?

Thanks,

Miguel

This should be pretty close to what you need:

data mysample1;

set mysample;

do year = year1 to year2;

output;

end;

drop year1 year2;

run;

If that's not it, perhaps you could explain a little more about what you are looking for.

Good luck.

Ah astounding you beat me right to it!

I also think what you are asking for is exactly accomplished by Astounding... I actually came to the exact same solution, a little late tho.
