Proc Freq questions

Say we have some data set called data1:

Name	Class	FS	Group	Good
Will	A	Maths	1	Y
Teddy	A	Phy	2	Y
Jeremy	B	Bio	3	Y
Bob	B	Maths	2	N

What SAS code would you write to generate frequency tables for each levels of Good (Y and N)?

. i.e.

Good=Y
	Class
Group	A	B
1	1	0
2	1	1
3	0	1
Total	2	2

Good=N
	Class
Group	A	B
2	0	1
Total	0	1

I guess proc freq is not the right procedure to create this type of table. You should try proc tabulate. It has lot of options to create different type of tables. Also, proc report might do it.

keeping it simple, is it not just a case of using a "by good ;" statement in proc freq?

a very basic test

data d1 ;

input

Name $ Class $ FS $ Group Good $ ;

list;cards;

Will A Maths 1 Y

Teddy A Phy 2 Y

Jeremy B Bio 3 Y

Bob B Maths 2 N

;

proc sort ;

by good ;

run ;

proc freq ;

by good ;

table group * class ;

run;

And even simpler, we could eliminate the sort and by statement, and use a three level table statement:

data d1 ;

input

Name $ Class $ FS $ Group Good $ ;

list;cards;

Will A Maths 1 Y

Teddy A Phy 2 Y

Jeremy B Bio 3 Y

Bob B Maths 2 N

;

proc freq ;

table good * group * class /nopct norowpct nocolpct ;

run;

Yes. It would be more simple , but not exactly look like the output OP want.
