三、相关分析1、概述整理化探资料时,需要研究许多变量之间的关系,例如各指示元素含量之间的关系,次生晕总金属量与矿体规模的关系,原生晕强度与离矿远近的关系等等.这些关系由于自然因素的复杂影响,并不能用一个确切的数学公式来表达,习惯上只采用定性描述或用图形表示.利用相关分析,可以更确切地表述各种地质变量之间的关系.具体说,相关分析就是从一套实际观察数据出发,通过一定的计
III. Correlation Analysis 1. General The data of geochemical exploration need to be studied for the relationship between many variables, such as the relationship between the content of each indicator element, the relationship between the total secondary halo total metal content and ore body size, the primary halo intensity Mine relationship, etc. These relations due to the complex nature of the natural factors, and can not be used to express an exact mathematical formula, the habit of using only qualitative description or graphical use of correlation analysis, can be more accurately describe the various geological Specifically, the correlation analysis is based on a set of actual observation data, through a certain meter
