Compare ID statement

[vandhan]

Can someone explain me Compare procedure ID statement use with simple example.

[Shmuel]

Do you mean using proc compare ?

Let have:

data A with 

       ID   VAR1

        1     25

        2     33

data B with

       ID  VAR1

        2     20

        3     50

Without ID statement comparison will be first row of A with first row of B etc.

With ID statement caomparison will be

             A ID=1 with no parallel in B

             A ID=2 with B  ID=2     etc.

Read the very fine SAS documentation for proc compare: http://support.sas.com/documentation/cdl/en/proc/69850/HTML/default/viewer.htm#n1nwxbchh5hpu1n1h28km....

It includes examples.
