Calculating totals

Jack1 — Mon, 29 Aug 2016 15:19:33 GMT

Hello,

I have a dataset that looks something like this:

	Type	Code	Date	Bankruptcy_Count
1	Sector	11	Apr-16	2
2	Sector	11	May-16	5
3	Sector	11	Jun-16	6
4	Sector	21	Apr-16	8
5	Sector	21	May-16	4
6	Sector	21	Jun-16	9
7	Sector	31	Apr-16	5
8	Sector	31	May-16	2
9	Sector	31	Jun-16	1

I want to create totals by month by inserting a new Type called "Total' with the code of 1. I would like the end product to look something like this with Total being included in the Type heading and Bankruptcy_Count the sum of the monthly sector values 11+21+31:

	Type	Code	Date	Bankruptcy_Count
1	Total	1	Apr-16	15
2	Total	1	May-16	11
3	Total	1	Jun-16	16
4	Sector	11	Apr-16	2
5	Sector	11	May-16	5
6	Sector	11	Jun-16	6
7	Sector	21	Apr-16	8
8	Sector	21	May-16	4
9	Sector	21	Jun-16	9
10	Sector	31	Apr-16	5
11	Sector	31	May-16	2
12	Sector	31	Jun-16	1

What is the easiest way to code this in SAS. Do I need to create a new dataset?

Thanks

Jack

One way, I can immediately think of create temp dataset with code 1 and append to your original dataset.

proc sql;
create table code_1 as
select  Type,
1 as Code,
Date,
sum(Bankruptcy_count) as Bankruptcy_count
from Input
group by 
Type, Code, Date;
quit;

proc append base= input data=code_1;
run;

Please try do until

proc sort data=have;
by date;
run;

data want(drop=count);
do until(last.date);
set have;
by date;
retain count;
if first.date then count=Bankruptcy_Count;
else count+Bankruptcy_Count;
if last.date then do;
type='Total';
code=1;
Bankruptcy_Count=count;
output;
end;
end;
do until(last.date);
set have;
by date;
output;
end;
run;

If you are just looking for a report, you should be able to get it without creating a new data set. (All of this is untested code so it may require some debugging.) Try PROC TABULATE:

proc tabulate data=have;

class type code date;

var bankruptcy_count;

tables (all all date) (type * code * date), Bankruptcy_count * sum=' ';

run;

There are many ways to make the table fancier, but that should be a good start.

Thank you!

Thanks Jag...one question.

The code you generated from my example would be for totaling values from three, two-digit codes by month. The totaled values go by the code '1' by month.

Let's suppose I need to expand this code to generate the same calculation for three-digit codes and four-digit codes and these need to be represented by the codes '2' and codes '3' respectively How do you modify your code to allow this loop?

Thanks

Jack

Thanks....that is helpful.

Suppose I wanted to create the same totals for the 2-digit sector but also the 3-digit sector as well:

1	Sector	11	16-Apr	2
2	Sector	11	16-May	5
3	Sector	11	16-Jun	6
4	Sector	21	16-Apr	8
5	Sector	21	16-May	4
6	Sector	21	16-Jun	9
7	Sector	31	16-Apr	5
8	Sector	31	16-May	2
9	Sector	31	16-Jun	1
10	Subsector	111	16-Apr	1
11	Subsector	111	16-May	3
12	Subsector	111	16-Jun	2
13	Subsector	211	16-Apr	4
14	Subsector	211	16-May	2
15	Subsector	211	16-Jun	4
16	Subsector	311	16-Apr	2
17	Subsector	311	16-May	1
18	Subsector	311	16-Jun	1

So the code would be modified to incorporate a loop so that I generate the monthly totals for each of the 2-digit (represented previously by code '1') and 3-digit codes (say represented by code '2')?

Thanks...Jack
