利用SAS软件对滕南煤田煤中碳、氢和发热量的回归分析

Regression analysis on carbon,hydrogen and calorific value of coal in Tengtian coal mine utilizing SAS software

使用SAS软件对枣庄矿业集团滕南煤田煤中碳、氢、发热量等数据进行回归分析,并分别建立了煤中碳与发热量的回归分析及碳、氢和发热量之间的回归分析。由计算的概率值表明,该矿区碳、氢、发热量等数据的测量值和计算值差异不显著,即回归方程的精度均达到了不同试验间的再现性要求。

SAS software was used to do the regression analysis of carbon, hydrogen and calorific value of coal from Tengtian coal mine of Zaozhuang mining group, and meanwhile, the regression analysis of carbon and calorific value and the regression analysis of hydrogen and calorific value were established. From the probability value calculated we can see that, there is no significant difference between the measurement values and calculation values of carbon, hydrogen and calorific value, which means that the precision of regression equation could not reach the reproducibility requirements among different experiments.
