Influence of sampling error on the value of correlation coefficient between geological and industrial parameters
Authors:
Abstract
The correlation coefficient as a measure of linear relationship between geological and industrial parameters (thickness of ore bodies, content of components in ores, etc.) is widely used in practice and has numerous applications. Meanwhile, the values of geological and 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 and industrial parameters. Let us consider the effect of sampling error on the value of the correlation coefficient between the grades of two components in the ore. ...
