Hallo All,

I am trying to fit a GAM regression to my data. However I have a question. So for instance if I have

Y = S(A) + S(B) as my GAM model,

Can I include a linear model of one variables, say B to the model. So that I get

Y = S(A) + B +S(B).

I do this because I want to obtain point estimates for the variable B. In that case how would this affect the interpretation of the smooth function. Can I say my smooth function S(B) shows the deviation from my average point estimates?

I would appreciate your support
