灰色预测与一元线性回归预测的比较

Comparing for Grey Forecast and Forecast of One Element Linear Regression

在介绍灰色预测和一元线性回归预测基本方法的基础上,用两个例子对两种方法的预测值进行了比较,结果表明:对所用的两个例子,灰色预测的GM(1,1)模型对数据的预测值精度较一元线性回归要好。

Based on the introducing the basic methods of grey forecast and forecast of one element linear regression, two examples are used to compare the accuracy of forecast value for two methods. The results show that the model GM （ 1,1 ） of grey forecast is better than one element linear regression in accuracy of forecast value for two given examples.
