ABSTRACT

Chapter 2 described the theory of multiple imputation. This chapter looks into ways of creating the actual imputations. In order to avoid unnecessary complexities at this point, the text is restricted to univariate missing data. The incomplete variable is called the target variable. Thus, in this chapter there is only one variable with missing values. The consequences of the missing data depend on the role of the target variables within the complete-data model that is applied to the imputed data.
