In planning the ongoing 6th Agriculture Census, a new Editing and Imputation System (E&IS) has been implemented, in order to reduce the total census error. The E&I System is a combination of different methodologies chosen and tuned on the basis of several simulations and validation tests, to verify the effectiveness of statistical methods adopted. In brief, the E&I strategy allows to identify the most appropriate method to solve problems of missing, invalid or inconsistent values in collected data, preserving the largest amount of available information. The following paragraphs describe the main features of the E&I System implemented. In particular, after deepening the E&I strategy, the fitting of the editing process in data collection stage is considered. As scheduled in the survey organization plan, the follow-up to the most relevant units, having anomalous values, has contributed to gather accurate information for the clerical review of outliers. Finally, the main editing and imputation steps and the adopted methodologies are highlighted.
