I have a data set sorted by social security number. I want to use (I think) a proc summary with an OUT = option that reports the number of times each social security number appears in the data set.
Maybe something like
proc sort data=allsets;
by ssn;
proc summary data=allsets out=ssn_count;
var ssn.
...<not sure about the rest>
Since it's a frequency count, perhaps use PROC FREQ instead?
proc freq data=allsets noprint;
table ssn/out=want;
run;

Yes, perfect. Thanks.
