Abstract:
|
Imputation methods are commonly and frequently used by survey practitioners. Our aim is to propose new, efficient, methods of imputation. We will focus on donor imputations that are a family of imputation methods where the missing value of a nonrespondent is replaced by the value observed for a respondent. Our method consists of formalizing imputation techniques as special sampling designs. Indeed, an imputation by donor can be viewed as the sampling of donors within the respondent population, where the order in the sample gives the correspondence between donors and receivers. We want to prepare for imputation by the construction of matrices of imputation that contain the probabilities for a nonrespondent to have his value imputed by that of a particular donor. Modern sampling techniques will then be applied on these matrices to realize an imputation. We establish a list of recommendatio
