How should I use fit definitive screening

Created: May 11, 2022 10:11 AM  |  Last Modified: Jun 10, 2023 4:48 PM (550 views)

I have a definitive screening design with 7 factors ( 6 continuous factors + 1 blcok factor) and 2 reponses. When I tried to use "Fit Definitive Screening" to analyze the data, I found I got totally 3 different results ( one each time and all use the same data). Every result has different "combined parameter estimates" and different" prediction profiler" and after I click "run model", each results will give me a predicted plot with different R square value. Can I get some suggestions on how to fix this?

To clarify, you are using the same data table and the "fit definitive screening" is creating the identical model for analysis?

 

Can you share your actual data table?  If not, can you anonymize it and share it?
