Borgoni, Riccardo and Berrington, Ann (2011) Evaluating a sequential tree-based procedure for multivariate imputation of complex missing data structures. Quality & Quantity (doi:10.1007/s11135-011-9638-3).
Item nonresponse in survey data can pose significant problems for social scientists carrying out statistical modeling using a large number of explanatory variables. A number of imputation methods exist but many only deal with univariate imputation, or relatively simple cases of multivariate imputation, often assuming a monotone pattern of missingness. In this paper we evaluate a tree-based approach for multivariate imputation using real data from the 1970 British Cohort Study, known for its complex pattern of nonresponse. The performance of this tree-based approach is compared to mode imputation and a sequential regression based approach within a simulation study.
