Hi everyone,
I am doing an optimization experiments with 3 factors at 3 levels of each variables, and I used Box-Benken design to design my experimental works. Total 15 runs was done and unfortunately, I do not know how to fit my data to the second-order popolynomial equation.
I did some preliminary analysis by Minitab 16, however I get so confusing that the model is fit or not best fit may data based on R-square, adjusted R-square and Lack of fit.
Please help me to explain more for me these issues. Many thanks for your kind helps
