In this case, we can also compare these values using Pearson correlation. Finally, trustworthiness indicators may be grouped into a trustworthiness matrix with the aim of representing the whole relationship table for each indicator: (4.21)Rtw=0rtw1,tw2⋯⋯rtw1,twn00rtw2,tw3⋯rtw2,twn⋮...

In the context of growing concerns related to the impact of mining activities on the environment, the present study focuses on the analysis of the correlations between the concentrations of heavy metals in Branch 1 and 2 tailing dumps in Lupeni, using Pearson correlation coefficient matrix. ...
Correlation Coefficient - Correlation MatrixKeep in mind that correlations apply to pairs of variables. If you're interested in more than 2 variables, you'll probably want to take a look at the correlations between all different variable pairs. These correlations are usually shown in a square ...
