Partial correlation coefficients in geochemical studies

Abstract

The techniques of correlation analysis as a method of statistical processing of the results of various determinations are now increasingly widely used in geochemical studies.Correlation analysis is used to assess the nature and strength of the relationship between chemical elements in paragenetic associations. For this purpose, regressions between two elements are most often studied by calculating and assessing the significance of pairwise correlation coefficients r. In the geochemical interpretation of regressions, it is necessary to take into account the possibility of influence on the selected relationships of other chemical elements present in characteristic associations ...
