Combining multiple imputation and meta‐analysis with individual participant data [PDF]

open access: yesStatistics in Medicine, 2013
Multiple imputation is a strategy for the analysis of incomplete data such that the impact of the missingness on the power and bias of estimates is mitigated. When data from multiple studies are collated, we can propose both within‐study and multilevel imputation models to impute missing data on covariates.
