Hello everyone,

I'm trying to analyze box behnken results . I have a question about r2 adjusted and refined r2 adjusted value. After refined a slight decrease occured r2 adjust value. I have found that the r2 adj value increased after refinery in nearly every study i reviewed and i read that it is positively interpreted on the suitability of the model. Could you please send me the references and explain the reason why the adjust r2 value decreased after refining?
