采用普通累积法和最小二乘法对某煤矿的一组基于γ辐射法测量煤中灰分的计数值进行回归分析,并对2种方法建立的回归模型进行对比研究,并用MATHEMATICA进行仿真对比,通过对结果误差分析,验证普通累积法的优越性。
Regression analysis was made on a set of count values of coal in a coal mine based on the gamma radiation method using ordinary cumulant method and least square method. The regression models established by the two methods were compared and compared with MATHEMATICA. Error analysis of results to verify the superiority of ordinary accumulation method.
