摘要
给出了背景函数为x(0)(t)=be-a(t+1)+c的精确级差格式,基于理想状态时的绝对误差提出了一种全新的灰色模型——灰色Gompertz模型.该模型具有良好的抗噪性,并且计算简单.实例表明了该模型具有良好的效果.
The precision grade difference format that background function is \$x\+\{(0)\}(t)=b\%e\%\+\{-a(t+1)\}+c, in the basis of ideal absolute error, the gray Gompertz model, which is a new gray model is exlained and discussed. The model has nice anti\|interference, and its calculation is very simple; the example manifest the model has good effect.
