六、多元线性回归分析 (一)方法概述及其在地质方面应用回归分析是研究变量间相互关系的一种统计方法,多元线性回归分析是研究某一变量与多变量之间的线性关系(非线性也可以转化为线性关系),它是以大量观测收集到数据为基础,找出相关变量之间的内部规律性,以定量形式建立一个变量与另一个变量(或另几个变量之间关系的数学表达式,从而可以根据一个或几个变量的观测值来预测(预报)另一个变量的估计值,并能从多个指标中找出对所研究的问题起重要作用的某些指标及它们之间转换关
VI. Multiple Linear Regression Analysis (I) Overview of Methods and Their Application in Geology Regression analysis is a statistical method to study the relationship between variables. Multivariate linear regression analysis is to study the linear relationship between a variable and multivariate Linearity can also translate into a linear relationship), which is based on a large number of observations collected data to find the internal regularity between the relevant variables, quantitatively establish a variable with another variable (or the relationship between the other variables So as to predict (predict) the estimated value of the other variable based on the observations of one or several variables and to find out from the multiple indicators certain indicators that play an important role in the problem under study and Switch between them off
