When Are Inferences from Multiple Imputation Valid?
نویسنده
چکیده
Multiple imputation, as described by Rubin, has seen a wide variety of applications. Counterexamples, presented by Fay (1991), and new methods, such as those of J.N.K. Rao and J. Shao, that can asymptotically disagree with the multiple imputation approach, have raised questions about the validity of multiple imputation. This paper identifies critical restrictions on the practical application of multiple imputation. It also discusses alternatives that can provide asymptotically valid inferences for some of the situations in which multiple imputation fails.

Inferences for Two-Stage Multiple Imputation for Nonresponse
Multiple imputation is a common approach for handling missing data. It allows users to make valid inferences using standard complete-data methods with simple combining rules. A variation is to partition the missing data into two portions and conduct the imputation in two stages. We review two-stage multiple imputation and existing inferential methods and derive an alternative reference F -distr...
متن کاملAnalyzing Imputed Survey Data Sets with Model Assisted Estimators
Multiple imputation has been previously applied for mass imputation, that is, the imputation from a subsample with complete information to a larger sample. In such applications, the missing data rates are often substantial, such as 80 percent or more, but valid inferences should, in principle, be within reach when probability sampling is used. Yet, limitations of multiple imputation can become ...
متن کاملOn using summary statistics from an external calibration sample to correct for covariate measurement error.
BACKGROUND Covariate measurement error is common in epidemiologic studies. Current methods for correcting measurement error with information from external calibration samples are insufficient to provide valid adjusted inferences. We consider the problem of estimating the regression of an outcome Y on covariates X and Z, where Y and Z are observed, X is unobserved, but a variable W that measures...
متن کاملAn Empirical Comparison of Performance of the Unified Approach to Linearization of Variance Estimation after Imputation with Some Other Methods
Imputation is one of the most common methods to reduce item non_response effects. Imputation results in a complete data set, and then it is possible to use naϊve estimators. After using most of common imputation methods, mean and total (imputation estimators) are still unbiased. However their variances (imputation variances) are underestimated by naϊve variance estimators. Sampling mechanism an...
متن کاملA method for increasing the robustness of multiple imputation
Missing data are common wherever statistical methods are applied in practice. They present a problem in that they require that additional assumptions be made about the mechanism leading to the incompleteness of the data. By incorporating two models for the missing data process, doubly robust (DR) weighting-based methods offer some protection against misspecification bias since inferences are va...
