proc report like decision tree diagram

carslan — Mon, 11 May 2015 09:11:26 GMT

Hallo All,

I have the dataset reports with proc reports:
info CW is calendar-week

	VAR1
	0			1
	VAR2			VAR2
	0	1		0	1
	VAR3	VAR3		VAR3	VAR3
	0	0	1	0	0	1
CW	sum	sum	sum	sum	sum	sum
15W01	120	300	15	20	2	3

But I want to have the report like decision tree diagram:

CW	VAR1
15W01	435			25
	VAR2			VAR2
	120	315		20	5
	VAR3	VAR3		VAR3	VAR3
	120	300	15	20	2	3
	sum	sum	sum	sum	sum	sum
	120	300	15	20	2	3

And so, for15W01, 15W02, 15W03, ….

I have only SAS BASE 9.4.

Can anyone know how to get this Report? Any help would be greatly appreciated.

Many Thanks,

Hi:

There are other procedures for SAS that do decision trees, but your example doesn't look like modeling. It looks more like a nested summary report. PROC REPORT and PROC TABULATE will both do summary reports, but won't "skip" variables on rows the way you show (such that VAR1 is in the middle. But, here's an example of what TABULATE would do for you (showing 15W01 only):

And, here's an example of what REPORT would do for you:

But of course, since you didn't post any input data, I had to make some fake data. So the structure of your input data will make a difference to the final code for you. For example, given that you said this was weekly data, I made a fake "DAY" variable, which you might not have in your data.

SAS does have procedures that do decision trees (PROC DTREE), but that is more for modeling than what you seem to show (simple SUM).

Hi Cynthia,

Thanks a lot for your support. Maybe my text was not clear. here is the data for only CW 15W01

data decison;

input CK $ VAR1 VAR2 VAR3 SUM;

datalines;

15W01 0 0 0 120

15W01 0 1 0 300

15W01 0 1 1 15

15W01 1 0 0 20

15W01 1 1 0 2

15W01 1 1 1 3

;

run;

with proc report I have this table like your proc report table

But I want to have this table.I want have SUM for every variable or class

I can do with 3 different proc report table. but I must do or show only one proc report table.

Thanks

Hi:

That is rather dicey to produce, since the header values are placed in PROC REPORT header cells, one row at a time. So, at the point in time AFTER the VAR1 has been written on header row 1 and AFTER the 1 and 0 have been written on header row 2, there is no visibility of the value that was just written in the previous row in order to write the 435 and the 25. So that will be a challenge you might get around with some kind of macro programming. But I do not think that this is really possible with PROC REPORT without at LOT of pre-processing of the data or the report. If you have presummarized all the totals, you might be able to do this with a custom TABLE template or with the Report Writing interface and a DATA step. But really, I am doubtful that PROC REPORT will be able to give you what you want. You might want to check with Tech Support before you start investigating other technology, though.

Hey, I know that this post is almost 4 years old, however, I am looking into something along the same lines. I have a Excel Template that displays data in a tree downward as subsets fo the the total. I was looking for Proc Report help to re-create this template, to reduce cut and paste to Excel.

What was you final solution?
