Discrete Grey Prediction Models

Abstract

This chapter mainly studies the latest research results related to discrete grey models, optimization of these models, approximately nonhomogeneous exponential growths, and discrete grey models of multi-variables. In the process of establishing discrete grey models, discrete forms of equations are employed throughout the stages of parameter estimate, simulation, and prediction so that no attempt of substituting either continuous or discrete models by the other is made, leading to relatively high degrees of accuracy.
