Title: A Comparison of Multiple Imputation and Other Unit-nonresponse Compensating Techniques in Fear of Crime Surveys

Abstract:

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 compare naive estimates, weighted estimates, estimates after a thorough nonresponse follow-up and estimates after multiple imputation (MI). For multiple imputation basically the flexible chained equations approach is used. A strong similarity between the MI-estimates and the follow-up-estimates is 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.
