STATISTICAL ACCURACY OF CONTINGENCY TABLES ESTIMATED WITH THE ITERATIVE PROPORTIONAL FITTING METHOD APPLIED TO THE HOUSING RELATED DATA OF POPULATION CENSUS : Case study of Tokyo metropolitan area

Abstract

In the census, cross tables for cities are rarely reported for more than two-ways. TO estimate such tables, proportional fitting method is frequently used. The statistical accuracy of this method is analyzed for housing related data. Two or more two-way tables or prefectural three-way table are necessary for estimating a three-way table. The average relative error is about 20% even in ideal cases.
