The focus of this study has been an analytic evaluation of the OveraIl edit and imputation system used by Business Division to process the Retail, Wholesale and Service segments of the 1982 Economic Censuses. The data employed in this study were not used for a statistical analysis of procedures and edit system actions, but rather these data served as a vehicle to track the flow of the system and were used as a concrete focus during our investigations. Two primary features in every edit and imputation system are subject-matter expertise and operational (often mathematical) procedures through which this expertise is exercised. Computer code is designed to integrate subject-based rules and operational procedures within a coherent framework and to direct the flow of records between the edit and imputation system and the ambient data processing environment an: within different segments of the system. In addition, features should be built into the computer code for an edit and imputation system that allow one to monitor its workings and aid in evaluating its performance.
