This paper aims to present some advances made in the development of a missing values and non-response imputation model for income variables in household surveys. The general methodological propose is exposed and the results of some tests. Two imputation methods are evaluated: 1) hot deck (widely used in mayor surveys such as Encuesta Permanente de Hogares –INDEC– and Encuesta Anual de Hogares of the Buenos Aires City) and 2) a LASSO regression model ensamble. The ensamble is generated using the bagging algorithm. The irst and second part of the document reviews the main missing data generation mechanisms and its implications for the use of imputation methods. In the third section, several imputation methods are reviewed, emphasizing its ass...
