Dear R users,
Below I have written 4 functions CIT1, CIT2a and CIT2b and CIT3 which
recode a variable CLD_ISCH into 3 new variables(T1 T2 T3), I wish to use
T1, T2 and T3 based on the values of tf1 and tf2.
(NOTE:- T2a is used to create T2 in a long winded manner due to my lack
of programming
Hi all,
I'm wanting to be able to find and store the z-score of coxph below: -
modz=coxph(Surv(TSURV,STATUS)~RAGE+DAGE+REG_WTIME_M+CLD_ISCH+POLY_VS,
data=kidneyT,method=breslow)
I know summary(modz) will give me this, but how do i extract the
standard error or z-score values in a similar way
Dear R Help list,
My question is regarding extracting the standard error or Z-score from a
cph or coxph call. My Cox model is: -
modz=cph(Surv(TSURV,STATUS)~RAGE+DAGE+REG_WTIME_M+CLD_ISCH+POLY_VS,
data=kidneyT,method=breslow, x=T, y=T)
I've used names(modz) but can't see anything that will let
Hi,
I've plotted a Kaplan-Meier curve but the curves only range from 0.7 to
1 on the y-axis. Therefore I have used: -
ylim=c(0.7,1)
[although I think convention dictates that you plot 0.5 to 1 to show the
median? A few papers I've read have done this]??
BUT, I would like a symbol like // (but
