模型从当日涨跌幅、开盘指数与收盘指数、涨跌日期等不同角度对股市的涨跌进
行分析和预测。
（1）选取2017年5月11日至2017年5月18日的当日涨跌幅度的数据，

Based on the basic principle of gray system theory and the GM (1,1) model, this
paper improves the classical GM (1,1) model which is also realized by
programming,according to the flow chart of finding the optimal weight automatically,
and also adopts the improved model to analyze and forecast the ups and downs 食用油 上市公司 of the
stock market from different angles which include the day of ups and downs, opening
index and closing index, the ups days and the downs days .
(1)The average relative error of the forecast is 5.67%, which is based on the data

Accordingly, the next three days of the stock index would fall mostly,and the degree 奔驰股票大跌
of change is 东吴轮动基金about -13.6.
(2)The average relative error between the opening index and the closing index is
0.46% and 0.17% respectively,which is based on the data of opening index and

is different.
(3)The date was selected from May 11, 2017 to May 19, 2017 when the stock
index is increasing during the the previous data processing,the model is
built to forecast. The results shows that the incline days are May 22, May 26 and May
