Output Grid Table feature under Prediction profiler grey-out/deactivated

[#1]

Hi,

I ran  a DOE that has 27 factors (continuous) and with a disallowed combination. The Output Grid Table feature is grey-out under the Prediction Profiler. I was thinking it could be too many factors. I reduced the total factors to 3 in the model and even tried to reduce the grid points to 2, the Output Grid Table remain grey-out. Can someone help to explain why this could happened and how I can force to activate it? I have 512GB of memory

Paste the picture of the grey-out feature mentioned above

Hi @dadawasozo,

The problem you face is not linked to the number of factors. If you have a large number of factors, a memory allocation message might be displayed for the grid table.

I think the Output Grid Table is greyed out because you have a design with disallowed combinations. Hence, it is not possible to create a grid since some combinations won't be possible. 
There are several alternatives :

• Use the option Output Random table 
• Use the Simulator, define the type of distribution you want for each of your factors, and then create the table
• Save your prediction formula, create a new table with the grid you want for your factors (by creating a custom design with discrete numeric factors or using Cartesian Join), and then paste the prediction formula of your original table on this new prediction table. 

Hope this answer will help you,
