One advantage that multiple imputation has over the single imputation and complete case methods is that multiple imputation is flexible and can be used in a wide variety of scenarios. Multiple imputation can be used in cases where the data is missing completely at random missing at random and even when the data is missing not at random.
Multiple imputation replaces each missing value by multiple plausible values. The variability between these replacements reflects our ignorance of the true (but missing) value. Each of the completed data set is then analyzed by standard methods, and the results are pooled to obtain unbiased estimates with correct confidence intervals.
