Correlation Matrix

The correlation matrix displays 2D scatter plots, histograms and the linear correlation coefficients calculated from the simulation results.

Home Screen Process Flowchart

1. Click on the Open the viewer icon in the contral bar on the Home Screen Process Flowchart window.

A New Plot window shall open.

2. Choose Correlation Matrix under Simulations.

 Correlation Matrix Settings

3. Select variables SIGY and T1 and response TOP_DISP for both Row and Column entities.

• The correlation coefficients are color-coded from blue to red. Blue indicates a strong negative correlation, red a strong positive correlation, whereas grey indicates almost no correlation.
• Moving the mouse on a scatter plot displays its ranges and marks the respective correlation coefficient with a yellow border, and vice versa.

 Correlation Bars

The coefficients of correlation of the responses and composites with respect to design variables can be displayed, along with their confidence intervals.

4.  Click on the New Plot button in the menu bar - (or click on the Open the viewer button on the Home Screen Process Flowchart as done for the first result plot).
5. Select Split vertical option on the left side to have this plot together with the correlation matrix.
6. Select Statictical Tools under Simulations.
7. Select Correlation as a Plot type in the Setup of new opened second plot (right side of the LS-OPT Viewer).
8. Select the response TOP_DISP to display its coefficient of correlation. The same values that are displayed in the last column of the correlation matrix, with additional information on the 95% confidence intervals.
