EMPIRICAL TESTS OF SOME SEMI‐SURVEY UPDATE PROCEDURES APPLIED TO RECTANGULAR INPUT‐OUTPUT TABLES*
检验了RAS、McMenamin-Haring和拉格朗日乘子三种更新方法在矩形投入产出模型双会计系统中的应用，发现这些方法在矩形表上的表现优于传统列昂惕夫模型。
ABSTRACT. This paper examines the RAS, M c Menamin and Haring, and Lagrange‐multiplier update methods in the context of the dual accounting system of the rectangular input‐output model. The motivation was to determine if the additional information contained in the dual system is exploitable, while maintaining the integrity of the rectangular structure with all its advantages. Tests were conducted on the performance of the various algorithms for a derivative Leontief model relative to their performance on the rectangular structure. The results obtained for rectangular tables were generally better than those obtained for the more conventional Leontief ones.
