Correlation Graphs

Figure 1 - Define Correlations Graphs

When creating or editing a correlation, the Graphs view of the Define Correlations window (Figure 1, right) provide visualizations of each input (in the form of a probability density graph) and the relationship between two inputs in the form of a scatter plot. These visualizations are included in a matrix using the same organization as the correlation matrix. The scatter plots indicate graphically how the sampled values of any two inputs will be related during a simulation.

Editing Coefficients

For correlations, the coefficients that determine how closely two inputs are related can also be edited from the Graphs view.

Figure 2 - Edit Coefficient

To edit a coefficient within the Graph view, double-click the graph of the coefficient to be modified. A field displaying the current coefficient value will appear (Figure 2, right); enter a new coefficient value or use the arrow keys to modify the value. Click outside the field to accept the new value.
