Hi all,
I've just finish an DOE test with 3 factors & the result is only 1 factors is statistically significant a.k.a having impact to the response. (meaning the remain factors have no impact/ too small impact vs system noise)
- Some pre-study & DOE result show that the noise is ~0.3
Here is the prediction profiler
I'm trying to use this result to predict the response & I'm considering 2 options that I don't know which one is the right way
- Option 1: Using DOE's profiler & predict by adding noise from system. Meaning I use the mean from predictive formular & add a random noise
- Option 2: I use the confident interval of response & adding noise from system. I create a new profiler when add the range of CI & add noise. (i'm thinking this one is better predict the real system)
So can anyone tell me which way is correct in my way.
And are there any better way can I do?
Thanks alot
