무시할 수 없는 무응답을 가지고 있는 교체표본조사에서의 무응답 대체와 교체그룹 편향 추정

Abstract

We propose proper methods to impute the item nonresponse in 4-8-4 rotation sam-ple survey. We consider nonignorable nonresponse mechanism that can happen whensurvey deals with sensitive question (e.g. income, labor force). We utilize modelingimputation method based on Bayesian approach to avoid a boundary solution prob-lem. We also estimate a interview time bias using imputed data and calculate cellexpectation and marginal probability on xed time after removing estimated bias. Wecompare the mean squared errors and bias between maximum likelihood method andBayesian methods using simulation studies.
