火烧云铅锌矿矿石小块体重多元线性回归模型建立及检验

Establishment and examination of multiple linear regression model of small volumetric weight in the Huoshaoyun lead-zinc deposit

运用Excel"数据分析"的"回归"功能模块建立了和田县火烧云铅锌矿区小体重多元线性回归模型,并对其质量进行拟合优度、误差分析、方程显著性检验(F检验)和回归系数显著性检验(t检验),证明在火烧云铅锌矿资源量估算中,运用多元线性回归方法确定小体重值是快捷便利、精确、科学的方法,也可以推广应用于其他贱金属矿床的资源量估算。

In this paper,″data analysis″ and ″regression″ functions of the software Excel were used to establish multiple linear regression model of small volumetric weight in the Huoshaoyun lead-zinc deposit in Hetian County. It carried out goodness of fit,error analysis,significance test of the equation（ F-test） and significance test of the regression coefficients（ t-test）. In resource estimation of Huoshaoyun lead-zinc deposit,this research proves that it is convenient,accurate and scientific to use multiple linear regression model to calculate the value of small volumetric weight. This method can also be extended to estimate the reserve of other base metal deposits.
