i've the following data

x1 x2 x3 x4

10 20 30 40

20 30 40 50

how do i calculate the skewness (using proc means) horizontally? i.e., for 10,20,30,40 and for 20,30,40,50?

If your data is horizontal and you don't want to transpose it just use the skewness function like so (I've added an extra row as your data shows a skewness of zero) otherwise you'll have to do a transposition.

data have;
	infile datalines dlm=",";
	input x1 x2 x3 x4;
	datalines;
10,20,30,40
20,30,40,50
2,3,4,90
;
run;

data want;
	set have;
	skew=skewness(x1,x2,x3,x4);
run;
