Multiple imputation for unit-nonresponse versus weighting including comparisons with nonresponse follow-up studies

The results of nonresponse follow-up studies from national fear of crime surveys are compared with results following the use of different nonresponse correction procedures. We compared naive estimates, weighted estimates, estimates after a thorough nonresponse follow-up, and estimates after multiple imputation (MI). For multiple imputation the flexible chained equations approach was used.

A strong similarity between the MI-estimates and the follow-up-estimates was found. This suggests that, if the assumption of the data missing at random (MAR) holds, carefully selected and collected additional data used in MI procedures could yield similar estimates to a nonresponse follow-up at a much lower price and respondent burden.
