Hi everybody, I have a question on multiple linear regression. I'd like to check several transformations of my independent variables (for example 1/x, x^2, sqrt(x)) in order to get a better adjusted r2. i have 5 independent variables (x1, x2, x3, x4, x5) and i would like to check the impact of different transformations at the same time. for example, one possibility would be y=1/x1+x2*x2+x3*x3+sqrt(x4)+1/x5.
in the end, the output would be the best fitted model.(crieterion=adjr2) can anyone help? thanks a lot
