Raking Ratio Estimation: An Application to the Canadian Retail Trade Survey
Michael A. Hidiroglou and Zdenek Patak
Abstract:National statistical agencies are increasingly using auxiliary information available from administrative sources. In this article, we will illustrate how auxiliary information can be used for monthly surveys collecting sales via ratio and raking ratio estimation. Although ratio estimation is widely used, raking ratio estimation has a number of desirable characteristics. It preserves auxiliary totals in all two or more dimensions. It also protects against outliers present in sparse cells, and ensures that the resulting calibrated weights are positive. We compare these two estimation procedures for the Canadian Monthly Wholesale and Retail Trade Survey.
