WitrynaMultiple Imputation (MI) as an imputation strategy for statistical analysis. Based on Bayesian theory-motivated underpinnings [5][6], MI allows the natural variation in the data to be emulated in addition to accounting for uncertainty due to the missing values in the subsequent inferences. In practice, the In order to deal with the problem of increased noise due to imputation, Rubin (1987) developed a method for averaging the outcomes across multiple imputed data sets to account for this. All multiple imputation methods follow three steps. 1. Imputation – Similar to single imputation, missing values are imputed. However, the imputed values are drawn m times from a distribution rather than just once. At the end of this step, there …
