Re: [R] Cox proportional hazard model and coefficients

his whole model-interpretation really confuses me. The final coxph-model was received by downward-selection using step-function.

[R] Cox proportional hazard model and coefficients

tty small and "easy to handle" numbers, e.g. coefficient = 1.73 -> exp(coef) = 5.64. BUT mine are way bigger numbers as you can see from the summary output (above). And because they are so large vaues, they almost seem to not make any sense. Grateful for the help, R-girl -- View

[R] Survival analysis and comparing survival curves

Hei, I have a one simple question which does not seem to be that simple as I cannot find any solution/answer: Is it possible to compare multiple survival curves in R with survdiff-function when there is interaction term involved in predictor variables (and this interaction is significant)? Examp
