基于背景值与初始条件优化的非等间距GM(1,1)模型
Unequal Interval GM(1, 1) Model Based on Optimization of Background Value and Original Condition
摘要
Abstract
The background value of the unequal interval GM(1, 1) model is optimized while its first accumulated generating series satisfy the approximate exponential rules. According to the method of least squares, the pending coefficient of the time response function is optimized when the sum of the squared differences of the first accu-mulated generating values and the simulative values is the smallest, then the unequal interval GM(1, 1) model optimized both the background value and the original condition is obtained. This optimized model doesn ’t need to select the initial condition, and an example is given to show the effectiveness and feasibility of this model.关键词
