Dear r-users, Does anyone know how to draw time-dependent survival curves?
Example: Event outcome: CHD Time-dependent covariate: NSAID use, which changes over time for each subject I'm interested in survival curves stratified by NSAID use. I'd like to implement Simon & Makuch (1984) method. Is there a R package/function to draw this graph? ------------------------------------------ Two related papers: Simon R, Makuch RW.
