Method* | Accommodation of Weighting in MI | MI Framework | Label |
---|---|---|---|
Complete case | No imputation completed. Analysis applied to observations with complete covariate data. | N/A | CCA |
Weight only | Imputation models include weights (through the outcome) as a predictor of missingness | FCS | FCS-WO |
MVNI | MVNI-WO | ||
Weight interactions | Interaction between outcome (proxy for weight) and exposure/covariates included in imputation model through passive imputation (FCS) or ‘just another variable’ (MVNI), in addition to outcome as a predictor. | FCS | FCS-WX |
MVNI | MVNI-WX | ||
Stratum specific imputation | Covariates imputed separately by weight status | FCS | FCS-SS |
MVNI | MVNI-SS | ||
Weighted model | Imputation model weighted with inverse probability of selection, outcome included as a predictor. | FCS | FCS-WM |
