A SAS® Macro for the Generalized RAS Algorithm

Coleman, Charles (2016): A SAS® Macro for the Generalized RAS Algorithm.

Abstract

Demographers and economists frequently encounter the problem of constraining matrices of mixed sign to controls of possibly mixed sign. The recently developed Generalized RAS (GRAS) algorithm is presented to solve these problems. The GRAS algorithm produces a unique solution that minimizes an entropy-like function. The algorithm is applied to a well-known example and compared to the solution originally obtained using a generalization of the Akers-Siegel procedure.
