Dear all,

 

I would like to calculate mutiple percentage by treatment and put it to one table . Is there any efficeint way for this ?

 

proc freq data = t ;

tables treatment *( d1  d2  d3  ................................ d100) ;

run;

 

With the following output table :

 

treatment       disease          count   percentage 

 

1                   d1

                     d2

                     d3

                     .......

2                    

                     d1

                     d2

                     d3

                 ..........

Thank you,

Transpose your data and use proc freq.

Thank you, I do not think that works .

Yes it does.

Why do you think it won't work? In fact, I think it was also suggested yesterday when you were looking for the maximum value.

Transpose worked for yesterday data, but not today's freq. The following is the codes I used, I am not sure whether this is the way you suggested . Thank you.

proc transpose data = ads out= ads_t;
by index_year ;
var COPD Chronic_kidney_disease
Congestive_heart_failure Coronary_Heart_Disease Dementia Diabetes HIV_AIDS Hemiplegia
Infectious_hepatitis Peripheral_vascular_disease Rheumatoid_arthritis Stroke Ulcer_disease
Venous_thromboembolism Alcoholic_liver_disease ;
run;

I would like to compare the different diseases percentage at different year. Thank you.

The word year doesn't appear in your initial post...

Please post sample data and sample expected output. You can make fake data for 5 or 10 d's rather than the full 100.

Thank you, Reeza.

Sample data:

treatment id d1 d2 d3
a 1 0 1 0
a 2 1 0 0
a 3 1 0 1
a 4 0 1 0
b 1 0 0 0
b 2 1 0 0
b 3 0 1 1
b 4 1 0 0

Output :

Treatment_a     Treatment_b     P-value 
d1 (percent)      

d2

d3

Because you've coded your data as binary, transpose and use proc means. Sum will provide count and mean will provide the percentage.

Thank you, Reeza. I just realized I forgot to add P-value to the output. So maybe I use proc freq to loop the variables and combine the output together instead of doing the task in one step.

I have no idea what you want anymore...good luck.

What test will you be running to get a p-value?
