线性回归分析在煤质检测结果审核中的应用

Application of linear regression in the examination of coal quality test results

利用石窑店煤矿2022年送检的80个样品的检测数据,采用线性回归方法,建立了5个相应的回归方程,经相关系数检查,证明5个相关方程均有实际应用意义。此回归方程可以用于检测报告审核,将实测结果与回归方程的预测结果进行比较,两者相差不超过回归方程标准差的2倍,即可以认为报告审核通过。

The article is based on theShiyaodian Coal Mine 80 test data submitted for testing in 2022,Using linear regression methods,Established 5 corresponding regression eguations,Checked by correlation coefficient,Prove that all 5 relevant eguations have practical applicaton significance.This regression equation can be used for inspection report review,Compare the measured results with the predicted results of the regression equation,If the difference between the two does not exceed twice the standard deviation of the regression equation,it is considered that the report has been approved.
