Stratified baseline graphical GOF test for Cox covariates in PH regression

Description

Looks at stratified baseline in Cox model and plots all baselines versus each other to see if lines are straight, with 50 resample versions under the assumptiosn that the stratified Cox is correct

Usage

gofG.phreg(x, sim = 0, silent = 1, lm = TRUE, ...)

Arguments

x	phreg object
sim	to simulate som variation from cox model to put on graph
silent	to keep it absolutely silent
lm	addd line to plot, regressing the cumulatives on each other
...	Additional arguments to lower level funtions

Examples

data(tTRACE)

m1 <- phreg(Surv(time,status==9)~strata(vf)+chf+wmi,data=tTRACE) 
m2 <- phreg(Surv(time,status==9)~vf+strata(chf)+wmi,data=tTRACE) 
par(mfrow=c(2,2))

gofG.phreg(m1)
gofG.phreg(m2)

bplot(m1,log="y")
bplot(m2,log="y")
