摘要
根据非等距GM (1,1)的建模原理 ,建立了非等距饱和指数曲线参数灰色辨识的二次一元线性回归解法。初步应用表明 ,本法计算简便 ,信息利用率高 ,拟合精度好 ,不仅为饱和指数曲线参数辨识提供了新途径 ,也进一步拓广了它的应用范围。
Based on the grey system theory,unary quadric linear-regression grey identification algorithms of non-equidistant saturated index curve parameter,is established for non-equidistant GM(1,1) forecast model A practical example shows the new method has high information utilization, good fitting precision and is easy to calculate The new method not only provides a new way for identifying saturated index curve parameters,but also further widens its application scope
