Random number generator processing element

In addition, the presence of the same element concentration (in our example, Th) in both the coordinates introduces a strong artificial correlation of no meaning in terms of process. Using a random number generator, e.g., in a spreadsheet, the reader may check that randomly and independently generated values of Ta and Th usually produce quite good correlations in Th/Ta vs Th diagrams. This topic is specifically dealt with in Section 4.2.
