Create freq crosstab matrix and for each combination calculate percentages of target var

sivakoya — Fri, 03 Feb 2017 16:34:22 GMT

Hi , I was working with this before and this has been answered in the post

https://communities.sas.com/t5/SAS-Procedures/Create-frequency-count-crosstab-matrix-and-for-each-combination/m-p/302505#M60713

I have a following dataset

ID   attribute1   attribute2   attribute3     BAD (Y-> yes)
1        1               0               0                 Y
2        1               1               0                 N
3        1               0               1                 Y
4        0               1               1                 N
5        1               1               0                 Y
6        1               1               0                 N
7        1               0               1                 Y
8        1               0               1                 N

I want to create frequency count matrix, for each combination of attribute tripped (atrribute = 1 means tripped) like following:

                         attribute1   attribute2    attribute3
attribute1                  _                3                  3
attribute2                 3                 _                 1
attribute3                 3                 1                  _

It represents counts of attributes tripped together.

Once i have the counts I need to calcualte %BAD in each combination like below.

                      attribute1     attribute2     attribute3
attribute1             _               12.50%         25%
attribute2        12.50%             _                   0%
attribute3            25%              0%                _

it represents out of 3 ID's for the combination atribute1 and atribute2 tripped, one ID went BAD -> so 12.5% BAD

And out of 3 ID's for the combination attribute1 and attribute1 tripped, two went BAD -> so 25% BAD

And the 1 ID for the combination attribute2 and attribute3 tripped, didnt went BAD -> so 0% BAD

I need to expand this analysis t0 3 variable combinations to get more meaningful results.

My dataset look like:

ID	grade	type	score	attribute1	attribute2	attribute3	attribute4	attribute5	attribute6	BAD (Y-yes/N- No)
1	A	1	100-110	1	0	0	1	0	0	Y
2	A	1	120-130	1	1	0	1	1	0	N
3	B	2	70-80	1	0	1	1	0	1	Y
4	C	3	30-40	0	1	1	0	1	1	N
5	A	3	40-50	1	1	0	1	1	0	Y
6	B	4	80-90	1	1	0	1	1	0	N
7	C	2	40-50	1	0	1	1	0	1	Y
8	C	4	30-40	1	0	1	1	0	1	N

Im trying to get to this analysis: I am showing values only for grade A as example:

				frequency Attributes/Attribute combinations
			Attribute1	Attribute2	Attribute4	Attr1&Attr4	Attr1&Attr2	Attr1&Attr2&Attr4
BAD	grade	score
yes	A	100-110	1		1	1
		110-120
		120-130
	B	90-100
		80-90
		70-80
	C	40-50
		30-40

No	A	100-110	2	1	2	2	1	1
		110-120
		120-130
	B	90-100
		80-90
		70-80
	C	40-50
		30-40

I was looking at http://www.datavis.ca/papers/sugi/mdarray/mdarray.pdf on mutildimensional arrays and mosaic displays. Wasn't quite sure how to get to such kind of analysis with this type of data. Any suggestions?

Thanks

SAS: Intersection counts for all combinations of column logicals (0/1)

Just the first part.

I recoded the 0s to missing so that proc corr would cout the non-missing intersecitons

proc summary may  work and be much faster?

Re: Create freq crosstab matrix and for each combination calculate percentages of target var

sivakoya — Fri, 03 Feb 2017 18:51:26 GMT

@rogerjdeangelis thanks for the solution for variable intersections. I also wanted to at the correlation at the combination of these variables.

ex:

two combinations:

A1, A2

A1, A3

A1, A4

A1, A5

A2, A3

A2, A4

A2, A5

A3, A4

A3, A5

A4, A5

Three occuring together:

A1, A2, A3

A1, A2, A4

A1, A2, A5

A1, A3, A4

A1, A3, A5,

A1, A4, A5

Four occuring together:

A1, A2, A3, A4

A1, A2, A4, A5

A1, A3, A4, A5

All five :

A1, A2, A3, A4, A5

sivakoya — Fri, 03 Feb 2017 19:05:59 GMT

@rogerjdeangelis

So if we look at it like a report I need to build something like this. Counts for various combination of these occurances.

A1, A2

A1, A3

A1, A4

A1, A5

A2, A3

A2, A4

A2, A5

A3, A4

A3, A5

A4, A5

A1, A2, A3

A1, A2, A4

A1, A2, A5

A1, A3, A4

A1, A3, A5,

A1, A4, A5

A1, A2, A3, A4

A1, A2, A4, A5

A1, A3, A4, A5

A1, A2, A3, A4, A5

BAD

grade

score

yes

100-110

110-120

120-130

90-100

80-90

70-80

40-50

30-40

100-110

110-120

120-130

90-100

80-90

70-80

40-50

30-40

Thanks

I am able to get till here. results of proc freq:

b	2	120-130	a1a2a3*a4	N	1
c	1	90-100	a1*a2	Y	1

I need to lay this out in a proc report format so i can get to :

BAD	Grade	Type	scorerange	a1	a2	a3	a4	a5	a1*a2	a1*a3	a1*a4	a1*a5

Re: Create freq crosstab matrix and for each combination calculate percentages of target var

AhmedAl_Attar — Sun, 05 Feb 2017 03:33:17 GMT

Try this

Run the TypeFormat macro declared in http://www2.sas.com/proceedings/sugi29/045-29.pdf, and then run this code

proc sort data=have out=srtd_have;
   by id grade type score_range bad;
run;

%TypeFormat(formatname=testtyp,var=a1 a2 a3 a4 a5);
proc summary data=WORK.srtd_have;
   by id grade type score_range bad;
   class a1-a5;
   ways 1 2 3 4 5;
   format _type_ testtyp.;
   output out=work.sum;
run;

Once the work.sum table is created, then you can slice&dice it as you want.

Hope this helps,

Ahmed
