回归分析法是用来研究某一变量与其他若干变量间的相关关系,定量预测某一变量如何随其它变量的变动而变化,通过数学统计法,建立一种定量的关系式来进行预测。回归分析法在地质工作中已广泛应用。如在多金属矿床中根据主要矿物与伴生元素的相关关系,预测伴生元素的含量;煤矿地质工作中,根据煤炭的灰份与发热量的关系,利用灰份含量预测发热量(反
Regression analysis is used to study the correlation between a variable and several other variables, to quantitatively predict how a variable changes with changes in other variables, and to establish a quantitative relationship through mathematical statistics to predict. Regression analysis has been widely used in geological work. For example, in the polymetallic deposits, the content of accompanying elements is predicted according to the correlation between major minerals and associated elements. In coal mine geological work, the ash content is used to predict the calorific value according to the relationship between ash content and calorific value
