| Tiivistelmä: | A problem that occurs in economics, urban planning, statistics, demography, and stochastic modeling is to adjust the entries of a large matrix to satisfy consistency requirements. These problems are known as balancing the matrix. Five applications of matrix balancing are described. Two scaling algorithms and a nonlinear network model for balancing matrices are described. The algorithmic and computational performance of these algorithms are compared with respect to their efficiency, applicability, quality of solutions, ease of use, and data requirements. A general discussion of these criteria is followed by results from a computational study of the algorithms on a set of large-scale balancing problems based on producing consistent estimates. |
