Hi. I am using MI to deal with missing data. My dataset contains longitudinal data over a 10 yr period (not all subjects are followed for the full 10 years however). In the data model stage, I am wondering if I should include the subject ID as a sample design variable to denote "clustering" of the data within subjects (ie. repeated measures on individuals). Is this appropriate?
Thanks for any input. Anne Anne Stephenson MD, FRCPC Divison of Respirology St. Michael's Hospital 30 Bond Street, Room 6-040 Toronto, Ontario M5B 1W8 Tel: 416-864-6060 x 4103 Fax: 416-864-5651
