The influence of sampling error on the value of correlation coefficient between geological-industrial parameters
Authors:
Abstract
The correlation coefficient as a measure of linear relationship between geological-industrial parameters (thickness of ore bodies, content of components in ores, etc.) is widely used in practice and has numerous applications. At the same time, the values of geological-industrial parameters are always measured with some error, which undoubtedly affects the value of the correlation coefficient and may even lead to an erroneous conclusion about the relationship between geological-industrial parameters. Let us consider the effect of sampling error on the value of the correlation coefficient between the contents of two components in the ore. ...
