Dear community,
i am using a cubical scheffe polynomial to model my system and i am having difficulties interpreting the analysis for one response. I am posting my analysis results for you to look at. Thanks in advance for your help.
This are estimates for the parametes and the effect tests
I have a very high r^2 which made me even more suspicious. r^2= 0.999 and of course very small residuals
Finally all the terms appear to be significant. Think is why i believe there might be some overfitting at work, but i am not sure.
