I would like to evaluate the influence of 8 factors on the response. There are 1 continuous factor, 7 other categorical factors, and 1 categorical response, and 2 of the categorical factors have 4 levels, one of the categorical factors has 8 levels. Can we use the classic screening design method to design experiments?
We want to know the most influential factors among the 8 factors, where we could analyze the screening experimental results? When we add more than 6 factors or the levels of factors exceed 3, the "Screening" tab disappeared where we cannot analyze the screening design results. What are the problems? Does that mean the classical screening design cannot be used in this case? Or we should analyze the screening design results separately?
Thanks.
