初值修正灰色预测模型的等价性
Equivalence of Grey Prediction Model Based on Modified Initial Value
摘要
Abstract
The equivalence of grey prediction models based on modified initial values is studied in this paper .By analyzing the structure of solutions for some grey prediction models , the authors prove that equivalence of grey prediction models , which modified ini-tial values are x (0) (1)+αandβx (0) (1), is related only with exponential structure of solutions , but has no influence on construction of background values and estimation of model parameters .The results reveal that the equivalence of grey prediction models based on modi -fied initial values is an essential characteristic existed in grey prediction model .关键词
