Dual System Estimation Based on Iterative Proportional Fitting

Written by:
RR84-03

Abstract

For a dual-system match between files from the Current Population Survey and the Internal Revenue Service we obtain population estimates. To minimize the effects of "correlation bias" we form these estimates within cells as narrowly defined as possible; yet in order to enhance stability of estimation we use iterative proportional fitting rather than cell-by-cell estimation, to estimate cell probabilities of match.
