煤炭价格预测模型及其应用

A coal price forecast model and its application

采用多元线性回归分析法和时间序列分析法建立了全国煤炭平均价格的预测模型,并将其较好地应用于2004年煤炭平均价格及其置信区间的预测。

Using the multivariate linear regression analysis technique and the time series analysis technique, a model for forecasting the coal mean price is constructed. With the model, accurate prediction is made of the mean coal price in 2004 and the confidence interval.
