WebSep 7, 2014 · In my previous post I wrote about the importance of age and why it is a good idea to try avoiding modeling it as a linear variable. In this post I will go through multiple options for (1) modeling non-linear effects in a linear regression setting, (2) benchmark the methods on a real dataset, and (3) look at how the non-linearities actually look. The post … Webtfun <- function (tform) coxph (tform, data=lung) fit <- tfun (Surv (time, status) ~ age) predict (fit) In such a case add the model=TRUE option to the coxph call to obviate the need for reconstruction, at the expense of a larger fit object.
