Alternative Approaches to Statistical Matching

Authors: Susanne Rässler;

Alternative Approaches to Statistical Matching

Abstract

Throughout this chapter we consider the matching problem as a problem of “file concatenation”, a term coined by Rubin (1986); see Figure 4.1. First the two files A and B are concatenated and then the missing values of each part are multiply imputed to reflect uncertainty about the missing data and the unknown association of the variables never jointly observed. Thus our task is again to impute the missing data of X in file A and the missing data of Y in file B. U obs file A denotes the variables Z and Y and in file B, Z and X, respectively. Basically, this is a classical imputation problem.
