Good morning, I'm currently learning JMP and about DSD/optimization. I ran my first experiment and would like feedback on the analysis and next steps. I'm using JMP Pro 17.
The experiment objective: Maximize the capture/recovery of bacteria to magnetic particles.
The setup: I picked out the 7 variables I thought could influence the outcome and tested them using 22 runs (2 blocks - it takes me 2 days to run that many samples). The model returned that 3 variables were significant but it appears that 2/3 of the variables could benefit from increasing the testing range. I say this based on the prediction profiler graphs. This is possible and feasible (to an extent) so I can retest them with a wider range.
1. Do I need to rerun the DSD with all 7 variables or should I just do a central composite design with the significant variables that covers the new ranges of those 2 variables? I'm leaning towards the CCD since I don't think the increased ranges will influence the insignificance of the other variables and then I can use the CCD to predict the optimal parameters.
2. I assume the DSD model could not predict the optimal parameters to use since I did not have the correct ranges, is this right? Or am I missing that output somewhere? I thought since <50% of my variables were significant that the design could then be used for optimization.
3. Am I missing something from the output that I should be looking at? Again, I'm new and the output has a lot of data to digest. My goal is to ultimately maximize the recovery of bacteria so I focused on what variables are significant and not really the rest of in the output. Are there specific "things" I should really focus in on/pay special attention to besides the alpha values? I did find some messages about the free online class for DOE so I will be taking that but I would appreciate specific feedback to my output so that I can "relate to" what that class will teach me with my own data.
I tried to attach the fit output but I keep getting an error message that the JMP file is not supported. I attached it as a PDF.
Thanks in advance for the help/feedback!
