Different results when forcing a quadratic model in fit model platform vs a simple square transformation
Hello Community, I have a question regarding a comparison of results between the results of a 2nd degree polynomial and a square transformation. To make things simple I created some mock data I'm gonna attach to this message, but here below a screenshot: For the polynomial approach, I did it on "fit model" platform and ticked "no intercept" option and also unticked "center polynomials" in the mod...
