Relative Risk/Hazard Ratio plots for continuous variables
...ons such as muhaz, survfit, coxph and cph that may enable
some plots to be produced but none that specifically look at the relative
risk one.
In addition to the survival analysis, I have incorporated the mfp function
(from package mfp).
I currently use code such as,
library(mfp)
library(Design)
coxfit1 <- coxph(Surv(rtime,rcens)~cts,data=data1)
or
coxfit2 <-
mfp(Surv(rtime,rcens)~fp(cts),family=cox,data=data1,select=0.05,verbose=TRUE)
plot(coxfit1) nor plot(coxfit2) produce the relevant relative risk vs.
continuous variable that I need.
Can anyone help?
Thank you,
Laura

Survival Plots by Strata
...e.g., min(Entry for each year)) is where each
curve begins at S_hat=1 for each year (and does not extend back to the
y-axis)? I could not find anything on this in the archives or MASS or
Survival Analysis using S? Anyone have a suggestion on where to look?
TIA, Bret
#Code snip for R email.
apc.coxfit1<-coxph(Surv(Entry, Exit, Fate)~Sex + Agerelease +
Dayrelease + strata(Year), data=mydat)
coxfit.apc<-survfit(apc.coxfit1)
coxfit.apc
plot(survfit(apc.coxfit1), conf.int=F, log=T, lty=c(1:2), col=c(1:2),
xlim=c(205, 800)) #not run--first entry for this example is day 205 for
1996, 259 for 1997...
