What Proc? - need sum stats of nested variables/group data of ind data

Hello, i have a data set which has all the individual observations. I'm trying to get a table/view which will give me the group data/summation of observations/not sure what to call it, which would look like the example of group data shown below. i.e. i have the data set which has each individual person who has responded to what look slike a survey denoting the following cahracteristics.

[pre] PreMarital Sex
1 2
Rel. Att. 1 2 1 2
Birth Cont 1 2 1 2 1 2 1 2

Political 1 99 15 73 25 8 4 24 22
Views 2 73 20 87 37 20 13 50 60
3 51 19 51 36 6 12 33 88
[/pre]

New to sas so not sure how to create this. I can index the variables but not sure if i should then be creating an array or a view or what.

Thanks! Message was edited by: CharlesR

Re: What Proc? - need sum stats of nested variables/group data of ind data

Hi:
You could do this kind of report (with nested counts) using either PROC REPORT or PROC TABULATE. It really depends on how you want the final look and feel of the report. You do not need to build arrays or views. PROC TABULATE is the greatest slicer and dicer of data invented and PROC REPORT runs a close second in the cross-tab department.

The only thing is that It will be hard to "label" the headers on the left, as you show (for Rel Att and Birth Control), but user-defined formats will make the meaning of each 1 and 2 clear. And PROC TABULATE comes closest to allowing you to label on the left, since you can put text strings into the TABULATE box area.

I used SASHELP.PRDSALE to fake up some data -- and picked some values for the user-defined formats. If you compare the results of the programs below, you can then decide whether to spend your efforts learning PROC REPORT or PROC TABULATE.
