How do I load factor tables into custom DOE - custom designs

Sammi_Chemist

Hey JMP community,

I'm struggling to load my factors and settings into the DOE - custom design platform...

Instead of specifying my factors directly into the DOE - custom design window, I would like to load the factor design table I have created.

Whenever I select "load factors" via the red triangle on the custom design page (photo 1), I encounter the following error (photo 2), "The current JMP Data table is not a valid factor table". For simplicity, the data table I am attempting to upload is like so (photo 3).

Any ideas what the issue might be? Thank you.

Hi @Sammi_Chemist,

Welcome in the Community!
I think what might be missing in your table are the column properties of the factors. These column properties help JMP understand how each factor should be considered for the design generation (and also used in some modeling platforms). In your example, you need to set these column properties :

• For numerical factors (like X1 and X3): Design Role (continuous), Coding (to understand what are the real uncoded high and low values in your design for each continuous factors) and Factor Changes (to understand what should the randomization structure of your design looks like based on how easily/frequently the factors levels can be changed).
• For categorical factors (like X2), you need to define the Design Role (categorical), Value Order (to understand the order between your levels and how they should appear in the different modeling platforms) and Factor Changes properties.

Perhaps the easiest way is to try create your design from scratch, and save the factors table to look at these column properties and how they are set up. You can also find information here : Add and View DOE Column Properties 

Hope this answer will help you,
