Dear Help desk,
I have a model that I believe to be non linear. The relationship is
Response = Var1 + Var1^2 + Var1^3
Can I examine this relationship using glm or lm? However, glm or lm gives
out pnly 1 coeficient for the model which is on Var1, unless I created some
dummy var like (Var2 = Var1^2 and Var3 = Var1^3).
Is there any other function handling this relationship?
My R is 0.64.2
