Weighting issue in Proc Tabulate

Bedi — Fri, 13 Jul 2018 12:09:15 GMT

I am trying to generate weighted percentages by using the below codes but it generates un-weigted percentages.

My weight variable is discwt

data redo_t1;
	input ID discwt 3.1 cat_flag race;
	datalines; 
		01 0.2 1 1
		02 0.4 1 2
		03 0.4 1 1
		04 0.4 1 2
		05 0.4 1 1
		06 0.1 3 2
		07 1.2 3 1
		08 0.4 3 2
		09 1.0 3 1
		10 0.4 3 2
	;
run;

proc tabulate data = work.redo_t1;
	title 'Table 1a';
	class cat_flag race ; 
	table race, (cat_flag)*(N colpctn);
	var discwt / weight = discwt;
	weight discwt;
run;

I don't know what you are trying to do here, but you can't weight a variable by itself. That simply doesn't make any sense from a mathematical point of view. Please type in the desired output from this data set, and how the desired output is computed, and perhaps someone can generate code to produce the desired output.

title 'with weights';
proc tabulate data = work.redo_t1;
	title 'Table 1a';
	class cat_flag race ; 
    var counter;
    weight discwt;
	table race, (cat_flag)*counter*(sum colpctn);

run;

Thanks for the revert.

I tried the code, it does gives me weighted count but the percentages from
'COLPCTN' are still unweighted.
