data x1y1
x1y0
x0y1;
/* x1y1, x1y0, x0y1 are output data set names */
merge left_most(in=x) right_most(in=y);
by id;
/* write all matches to x1y1: */
if x=1 and y=1 then output x1y1;
/* non-matches from the left-most data set: */
if x=1 and y=0 then output x1y0;
/* non-matches from the right-most data set: */
if x=0 and y=1 then output x0y1;
run;

If you could design your ideal job, what would it look like?
data abc; input x y ; cards; 1 2 5 6 7 8 7 8 1 7 5 7 ; run; Proc Freq data=abc; tables x*y / chisq nopercent nocol norow PLCORR; RUN; If we run the code, we have Polychoric Correlation = 0.9054 in the last table. I want to extract this particular entry with the value. Means I will create one dataset in which this value will be stored/extracted. I need your help in coding this. Please help me out.
