Estimating age change in list recall in asset and health dynamics of the oldest-old: the effects of attrition bias and missing data treatment.
Kennison RF, Zelinski EM. Kennison RF, et al. Psychol Aging. 2005 Sep;20(3):460-75. doi: 10.1037/0882-7974.20.3.460. Psychol Aging. 2005. PMID: 16248705
In Study 2, models that included dropout status had better fits and reduced random variance compared with models without dropout status. The authors conclude that change estimates are most accurate when independent predictors of missingness are included in the treatment of …
