Hi all
To control for confounding bias from non-random treatment assignment with 3 different treatments, I would like to calculate a propensity score I later can use in a cox regression model. I know the procedures for a two-treatment approach (logistic regression). But how would I calculate such a score when I have three treatments?
Thanks in advance
Christian
