[关键词] GM(1,1)模型CPI指数灰色预测 消费者物价指数(Consumer Price Index),英文缩写为CPI,是反映与居民生活有关的商品及劳务价格统计出来的物价变动指标,通常作为观察通货膨胀水平的重要指标。如果消费者物价指数升幅过大,表明通货膨胀已经成为经济不稳定因素,央行会有紧缩货币政策和财政政策的风险,从而造成经济前景...
a灰色预测是对既含有已知信息又含有不确定信息的系统进行预测;灰色预测模型GM(1,1)具有思路简单、数据单纯、运算简便等特点,对样本含量和概率分布都没有严格要求,能更好考虑时间序列资料的发展变化情况,预测效果令人满意。 The gray forecast is to both includes the known information and to include the indefinite...
