Proc tabulate calculating percentage

Martinez77 — Wed, 21 Aug 2013 15:29:03 GMT

Hey all,

1.I need to calculate a percentage in proc tabulate. I am trying to sum a variable (totalsch) then find it's percentage of the column total.

I believe the code below would do that, however, when I check the calculation the percentage is incorrect.

Any thoughts?

proc tabulate data = Collegeofmusic style=untpdf;

class acad_plan acad_term_desc;

var totalsch;

Table acad_plan All='Total',acad_term_desc*totalsch*(sum colpctn) ALL='Total';

run;

Thanks Martinezz

It sounds like you are looking for colpctSUM rather than colpctN.

Astounding,

Perfect, thank you very much. Out of Curiosity what is the difference between the two?

Both get you column percentages, but ...

colpctN computes percentages based on the N statistic (number of observations with a nonmissing value for the analysis variable)

colpctSUM computes percentages based on the SUM statistic (sum of the analysis variable)
