Subject: Case and Control Matching
Does anyone have SAS code that will perform a one to one (or one to many
match) on a group of cases and controls. The key is that once a control
matched to a case, that control should be removed from the list before
continuing the match. Meaning -- a control can only be matched once, to a
case. Thanks very much for your help,
