Dear community,
I used a cubical Scheffe Polynomial to describe my experimental system and I got very weird results for one of the responses, results that are too good to be true.I have a r2 of I will post the rest of the results for the response. Thanks in advance for your help.
These are the parameter estimates and the effect tests
Estimated response is plotted against the measured response and the residuals are plotted against the predicted response
Finally what makes me very suspicious is the fact that every term seems to be significant. Which leads me to believe that there must be an overfit.
