st: RE: duplicates drop
You may use:
drop if _m!=3
this will drop records both from 'master' as well as 'using' dataset which are not uniquely identified.
However, be warned of using -drop- command, you may lose some vital info..

Subject: st: duplicates drop
Dear all,
I merged two dataset for a pre-study. In this study, I can not uniquely
identify some cases since I do not have access to all variables.
How can I drop all cases which have duplicates? I know about the command
"duplicates drop". However I would like to drop all cases which are not
unique, not only the duplicates.
Thanks for your help
Simon
