Hi all, Is there an equivalent to predict(...,type="linear") of a Proportional hazard model for a Cox model instead?
For example, the Figure 13.12 in MASS (p384) is produced by: (aids.ps <- survreg(Surv(survtime + 0.9, status) ~ state + T.categ + pspline(age, df=6), data = Aidsp)) zz <- predict(aids.ps, data.frame(state = factor(rep("NSW", 83), levels = levels(Aidsp$state)), T.categ = factor(rep("hs", 83), levels = levels(Aidsp$T.categ)), age = 0:82), se = T, type = "linear") plot(0:82, exp(zz$fit)/365.25, type = "l", ylim = c(0, 2), xlab = "age", ylab = "expected lifetime (years)") lines(0:82, exp(zz$fit+1.96*zz$se.fit)/365.25, lty = 3, col = 2) lines(0:82, exp(zz$fit-1.96*zz$se.fit)/365.25, lty = 3, col = 2) rug(Aidsp$age + runif(length(Aidsp$age), -0.5, 0.5), ticksize = 0.015) Is it possible to achieve something similar with a Cox model instead? Is there a more detailed explanation of the "type" option for predict.coxph than what's in the help of predict.coxph? e.g. type=c("lp", "risk", "expected", "terms") thanks in advance, Ben ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
