Before revision:  By using the Dempster combination rule and confidence function based on the entire time series fused at each time pointand future time points, and the preliminary forecast value obtainedthrough the time relationship, the accurate forecast value can be restored. This article will introduce the prediction method of evidence theory .
After revision:  By using the Dempster combination rule can be used to fuse the growth rate of the last time point, and finally a relatively accurate forecast data can be obtained. Stock price forecasting is a concern of economics. The stock price data is large in volume, and more accurate forecasts are required at the same time.
