Subject: st: Interaction between two splines?
Dear All,
I am doing a discrete time hazard model. I have two continuous variables
whose functional forms are not knwon. Linear spline seems to be a good
choice to check the functional form. Now I also want to include their
interaction terms, can I multiply the two splines like multiplying two
sets of dummy variables? I don't remember have read anywhere about how to
interprete spline interactions. Thanks!
