Percentage of independent, joint and total explained variance for each considered variable.

Total: Total explained variance, correlation (in “R2”) of each of the variables with the response variable (for example, XA, XB, XC and XD have a correlation coefficient with the response variable Y, r<0.10, i.e. each of them explain <1% of the variance of the response variable, r2<1%). Joint: Negative joint variance indicates that the other variables act as suppressors of the particular variable. Variables: The variable order shown in the tables is the order used (i.e. alphabetic order) for this particular analysis of hierarchical partitioning.
