“…While we agree that treating the imputed values as if they were observed values tends to lead to variance estimates that are too small (and ultimately to confidence intervals that are too narrow), we believe that this criticism is not justified because it ignores a wide literature on variance estimation procedures for singly imputed data that have been developed in the last two decades in a survey sampling setting, e.g. Rao & Shao (), Särndal (), Shao & Sitter (), Shao & Steel (), Beaumont & Bocci (), Haziza (), Kim & Rao (), among others. Several variance estimation procedures for producing consistent variance estimators are currently available in the literature.…”
