煤炭发热量与灰分回归模型的建立

Research on the regression model between calorific value and ash content of coal

提出一种数据预处理方法 ,并将它应用于煤炭发热量和灰分的原始数据预处理。经预处理后的数据 ,运用多项式回归建立了煤炭发热量与灰分之间的回归模型。方差分析和交叉验证表明 ,该模型具有好的显著性和稳定性。

An approach of data preprocessing was proposed in this paper.The approach was applied to process the original data of calorific value and ash content of coal.After data preprocessing,a regression model between calorific and ash content was founded by polynomial regression.The variance analysis and cross_validation indicate that this model is notable and steady.
