Aliasing of Effects with a foldover design

anne_sa — Wed, 15 Jun 2016 10:17:07 GMT

Hello,

Here is my problem:

First I create a screening design (7 factors and 8 runs). In the DOE dialog window, I can check the Aliasing of Effects before creating the table.

Then I would like to add more runs. To do that I go to the platform Augment Design and I create a foldover design.

I would like to know what is the aliasing structure of this new design however I do not know where I can find this information.

Could you help me please?

Thanks in advance!

After you create and save your augmented design then just use the Evaluate Design capability to examine.

Thank you for your answer Lou Valente.

If I look at the Evaluate Design report, I see the alias matrix which indicates me which interactions are confounded with the main effects.

However I would like to know which two-factor interactions are confounded with other two-factor interactions. How can I get that ?

Anne,

I use the Color Map on correlations and hover over the red boxes to see the alias structure but one can also use the Modeling>Screening platform which delineates the alias. There may be additional ways but I figured I'd share these.

That is exactly what I was looking for.

Thanks again Lou Valente.
