I have a problem in SAS which is the following: For several firms I have several people (directors) for 6 different years. I wish to pick one person from each firm, who has all six years of observations and perform a regression analysis on these people. So I need help to get one person from each firm with all sex years of observation. I have a firmID, DirectorID and a Year variable (from 2002-2004 and from 2006-2008) I you need more detail on the problem please let me know! Thanks!
