济宁市翟村铁矿小体重值与磁性铁品位的回归分析

摘要

By using weight test value and magnetic iron ore grade data obtained in the course of exploration of Zhai-cun iron deposit in Jining city,regression analysis has been carried out,and gained the regression equation y=2.74+0.026x.After significance and precision test,combining with actual practices,it is proved that regression equation has significance and high prediction accuracy.By using this equation,the value of a small weight of Zhai-cun iron deposit can be predicated.%利用济宁市翟村铁矿勘查过程中取得的体重测试值与磁性铁品位数据进行了回归分析，得出回归方程为y＝2．74＋0．026x，经显著性、精度检验并结合实际实践，证明该一元回归方程具有显著性，预测精度较高。可以用该方程预测翟村铁矿区小体重值。
