Hello folks,
I am wondering how to do survival analysis with time-related IVs in R. For
example,
> > If we have time-related variables, such as the Overall Condition of
1990, 1991 etc., how can we include these variables in coxph model?
> >

make it something like:
> > ID time age drug censor Year Overall Condition
> > 1 1 5 46 1 0 1990 XXX
> > 2 1 5 35 1 0 1991 XXX1
> > 3 1 6 35 1 1 1992 XXX2
> > 4 2 5 46 1 0 1990 XXX
> > 5 2 6 35 1 1 1991 XXX1
> > 6 3 6 35 1 1 1990 XXX2
And then run logistic regression using "censor" as the DV?
