Is it possible to get a plot of an interaction term entered into a cox
regression by using the plot command directly? I have one dichotomous
variable and one categorical variable with 4 categories that is used in an
interaction term and I want to plot the survival curves for the interaction
terms when controlling for all the variables used in the cox regression. Can
this be done without having to recode the 2 variables into some kind of new
variable? Likewise I have an interaction term with one dichotomous variable
and one continuous variable and I would like to make a plot of this
interaction term as well.
Anybody able to give me some advice?
Thank you in advance,
Claus
