Hello,

I have a question about the analysis of a response surface design.

In my design I have 4 factors and 3 responses.

I launch the fit model platform (which is already completed by JMP) then from the Effect Summary I remove the non significant effects. After that I look at the Prediction Profiler and I maximize the desirability regarding my 3 responses.

However some effects are not significant for all responses. Thus I wonder if I should rather run an analysis for each response separately, keep only the significant effects in each model (so I may have 3 different models), save the prediction formula and finally launch the Profiler Platform from the Graph menu to maximize desirability.

What do you think about that?

Thanks in advance for your advices!

Re: Question about response surface analysis

I concur with Ian. In fact, we generally recommend this practice in training whenever there is more than one response. Taking this idea a step further, it means that you can model each response with the best possible model: linear model, neural network, and so on and then combine them for optimization. Also, you might have models to be included in the optimization that came from experiments or theory from the past. This set up is very flexible.

Learn it once, use it forever!
