摘要
M GM(1,n)预测模型同样存在理论缺陷,即在形成预测公式时规定^X(1)(1)为已知条件是不合理的,应当根据实际情况选用其他数据.对原公式进行了修正和拓广,给出了新的预测公式,为提高预测精度提供了新的途径.
Grey prediction formula of MGM（1,n） has theoretical defect also, that is X^（1）（1） shouldn＇t be limited as the only known condition when forming the prediction formula. Instead, other data could be used. This paper modifies and expands the old formula, proposing new formula, and gives new way to improve the prediction accuracy.
