Pareto diagram

Design Exploration Plots Pareto diagram

Pareto diagrams only apply on DOE Full Factorial and Central Composite techniques.

A Pareto diagram is used to determine which factor (or group of factors) is the most influential regarding a response.

A Pareto diagram is a bar chart. Each bar represent, the contribution in percentage of a factor or group of factors on the variation of a given response.

A red bar means that the contribution is positive while a blue bar means that the contribution is negative. A factor has a positive contribution if the value of the response increases when the factor goes from low to high level.

When Pareto diagram is selected, the dynamic part of the dialog box is as shown in the following figure.

Figure 108: Setup of a Pareto diagram

Select the response you want to analyze using the drop-down list and click on the OK button.

If you do not want to display meaningless factors, set a threshold which is not 0: the factors or group of factors with a contribution smaller than the threshold value will not be displayed.

You must wait until the end of the design exploration process to create such a plot.

This type of plot cannot be updated.
