Using EWMA to forecast the portfolio's dynamic transferred variance-covariance matrix, we can get more reasonable and precise dynamic transferred coefficient matrix.
Based on the convex simplex method for nonlinear programming, a sensitivity analysis of consumption coefficient matrix in linear fractional programming is presented.
According to actual economic meaning, RAS method and the positive characteristic vector method, this paper gives a technique to adjust direct consumption coefficient matrix in inverse way.
The method ICCG. is one of the best iterative method for solving the system of linear algebraic equations, but it can only be applied to the symmetric and positive definite coefficient matrix.
