Proc means output n=xn

[DmytroYermak]

Hi all,

Can you please say what does option value 'xn' mean?

Here it is the proc means:

PROC MEANS DATA  = F1 NOPRINT;
	CLASS COL0 COL1 COL2; 
	VAR D ;
	OUTPUT OUT = F_MEANS N=XN;
RUN;

N= is the option meaning the count or frequency. XN is the name of the variable you are storing the value of N=.

XN is the name of the variable created by PROC MEANS that contains the count (because it is create by N=) of non-missing values of variable D
