Correlation Matrix

By viewing the correlation matrix of variables against responses, we can also find out the most correlated variable to the maximum percent thickness reduction.

 

Open a new Viewer: menubar1.png

  1. Restart the LS-OPT Viewer by clicking on the first icon on the menu bar.
  2. Select Correlation Matrix.newplot2.png

  1. Disselect Response for Row entities.
  2. Disselect Variable for Column entities.
  3. Now we obtain a matrix showing all the correlation coeffients between variables and responses. From the first column we find that the variable YIELD has the largest absolute value of the correlation coffient with the maximum percent thickness reduction, whick coincides with the fact we've seen before.

 

 

 

 

 

 

 

  •  We can verify this fact in different ways (also see Correlation Bars and Scatter Plots).
